Unravel the mysteries of ultrasound scans during pregnancy. Understand their significance, what to expect, and their role in ensuring a healthy pregnancy. Experience the joy and reassurance that comes with seeing your baby’s first images.

Embarking on the journey of pregnancy is a thrilling yet complex adventure, filled with excitement, anticipation, and a myriad of questions. Among the most common queries we encounter at our clinic is the significance of ultrasound scans during this special time. Understanding the importance of these scans, often shrouded in mystery, can profoundly change perceptions, transforming them from just a clinical procedure into an invaluable and cherished part of the pregnancy experience. These scans can be done from week 6, as this is when we reach the first major developmental milestone.

The Role of Ultrasound in Pregnancy

Ultrasound scans, a window to your womb, offer a non-invasive peek at your developing baby. Ultrasound technology has revolutionised prenatal care since its inception. Initially utilised in the 1950s for gynaecological purposes, its application in monitoring fetal development during pregnancy was a groundbreaking discovery that has shaped modern obstetrics. The development of the first contact B-mode scanner opened a new window into the womb, allowing for the visualisation of the fetus and transforming prenatal care.

This innovation marked the beginning of using ultrasound to monitor the baby’s development, detect potential abnormalities, and even predict birth weight discordance in twin pregnancies. Today, ultrasound scans are a routine and indispensable part of prenatal care. Most women are offered at least two standard scans during their pregnancy. The first scan, usually conducted between 10 and 13 weeks, is crucial for confirming the due date and checking the baby’s heartbeat. The second scan, typically between 18 and 21 weeks, focuses on assessing the baby’s growth and anatomy in more detail.

What to Expect During an Ultrasound

Understanding what happens during an ultrasound can ease any apprehensions and make the experience more enjoyable. At London Pregnancy Clinic, we encourage patients to ask questions and see this as an opportunity to educate them about the wonders of ultrasound and pregnancy.

Procedure: You’ll recline on a comfortable bed in our serene scanning room. While ‘internal’ and ‘external’ aren’t official medical terms, they are commonly used to describe ultrasound methods. An internal scan, often a transvaginal ultrasound, involves a probe inserted into the vagina for detailed pelvic images. Whereas, the external scan is an abdominal ultrasound, where a transducer glides over the abdomen to visualise the baby and internal organs. Our specialists excel in both types of ultrasounds, providing thorough care and support throughout your pregnancy.

Scanning: While our specialists move the transducer, you may feel slight pressure, but it’s generally a painless process. Traditional 2D ultrasounds provide clear images of your baby’s structure, while advanced 3D and 4D technologies can offer more detailed views, such as facial features or specific organs.

Duration: A standard ultrasound typically lasts about 20 minutes. However, at London Pregnancy Clinic our scans, are more comprehensive and may take up to 30/45/60 minutes. Occasionally, obtaining clear ultrasound images can be challenging. Factors like the baby’s position, movement, body composition, or higher body weight might affect image clarity. However, this is usually no cause for concern. To enhance image quality, we might ask you to take a short walk. This can encourage the baby to shift position. 

Results: At LPC we use Tricefy to share the images and reports with you. It’s important to note that ultrasounds are safe, with no known risks to either the baby or the mother. However, they are an important diagnostic tool, providing valuable information for any potential medical decisions.

What is an Ultrasound Probe

An ultrasound probe, or transducer, directly contacts your body during an ultrasound. It plays a crucial role in both sending and receiving sound waves to create clear images of your baby. Here are the key details you should know:

Piezoelectric Crystals Inside: These crystals change electrical energy into sound waves and back, enabling the probe to send and receive signals.

Varied Shapes and Sizes: Probes differ based on their use. They range in frequency and field of view. Lower frequencies (2.5-7.5 MHz) penetrate deeper, making them ideal for viewing internal structures. Higher frequencies (above 7.5 MHz) offer better resolution for closer, superficial areas.

Different Types for Different Uses: There are external, internal, and endoscopic probes. External ones glide over the skin, internal ones go inside body cavities, and endoscopic ones, attached to a tube, are inserted into the body for closer examination.

Handling with Care: Dropping or improper cleaning can damage probes. They require careful handling to maintain their precision and effectiveness.

In summary, ultrasound probes are essential for generating and receiving sound waves that provide us with valuable images of the internal body structures of your or your baby. Check out our YouTube video on ‘What are Ultrasound Probes‘.

NHS Ultrasound Scans

In England, the NHS provides crucial ultrasound scans during pregnancy at key stages. Hospitals in England offer at least two ultrasound scans, conducted by fetal medicine practitioners, which include the following:

  • 12-Week Scan (Dating Scan): Offered between 11 and 14 weeks, this scan estimates your due date. It may include a nuchal translucency (NT) scan (this is an NHS scan not to be confused with our private Nuchal Scan), part of the combined screening test for Down’s syndrome (Trisomy 21). This screening includes a blood test and an ultrasound scan. The scan measures the fluid at the back of the baby’s neck, also known as nuchal translucency. However, unlike Non-Invasive Prenatal Testing (NIPT), it is not considered the most advanced and modern way to screen for Down’s and other chromosomal syndromes.
  • 20-Week Screening Scan (NHS Anomaly Scan): Conducted between 18 and 21 weeks, this scan, also known as the anomaly or mid-pregnancy scan, checks for 11 physical conditions in the baby. These include Spina Bifida, Anencephaly, Cleft Lip, Diaphragmatic Hernia, Exomphalos, Serious Cardiac Abnormalities, Bilateral Renal Agenesis, Lethal Skeletal Dysplasia, Edwards’ Syndrome (Trisomy 18), Patau’s Syndrome (Trisomy 13), and Acrania. 

LPC Ultrasound Scans

Following the essential scans offered by the NHS, the London Pregnancy Clinic presents a spectrum of specialised ultrasound scans for expectant mothers. While we endorse the significance of NHS scans, our clinic provides additional, detailed insights into your baby’s development. We are renowned for our proficiency in early anomaly detection but we offer an extensive scan list designed by Dr Fred Ushakov:

Our clinic’s dedication to fetal medicine is evident in our use of the latest imaging technologies, including 2D, 3D, and 4D scans. These technologies allow us to screen various aspects of your baby’s growth and development, providing reassurance and a deeper connection with your baby throughout your pregnancy journey.

Ultrasound scans during pregnancy FAQs

  • Difference between internal and external ultrasound scans

    Internal Scan (transvaginal scan) – involves inserting a specially designed probe into the vagina. Provides high-resolution images of the pelvic organs, including the uterus, ovaries, and in early pregnancy, the developing fetus. Commonly used in early pregnancy stages for clearer and more detailed images. In an abdominal ultrasound, a sonographer applies a water-soluble gel to your belly and uses a transducer to glide over the skin, sending sound waves that create images of the baby.

    External Scan (abdominal scan) – this method involves moving a transducer over the abdomen’s surface. It captures images of internal organs, including the developing baby, placenta, and uterus during pregnancy. Used throughout pregnancy, especially in the second and third trimesters, to monitor the baby’s growth and development. In a transvaginal ultrasound, a longer and thinner transducer is gently inserted into the vagina to get closer to the uterus, offering detailed images, especially in early pregnancy.

  • How many ultrasound scans can I have during pregnancy?

    During pregnancy, the number of ultrasound scans you can have varies:

    • NHS Scans: Standard NHS care includes two scans. These check the baby’s size, detect abnormalities, determine the due date, and monitor growth.

    • London Pregnancy Clinic Options: We offer additional scans for more comprehensive screening and reassurance:

      • Early Fetal Reassurance: Includes 2 early scans for early health screening.
      • NHS Complementing Scan: Features 3 scans alongside the standard NHS 12-week and 20-week scans.
      • Comprehensive Scan Package: Provides 6 scans, ideal for high-risk, IVF pregnancies, or those after a miscarriage.

    While you can theoretically have as many scans as you wish, it’s about balancing the benefits with your time and energy. Our packages at London Pregnancy Clinic are designed to complement NHS care, providing peace of mind throughout your pregnancy journey.

  • Can an ultrasound scan harm me or my unborn baby?

    Patients are often concerned about whether or not ultrasound scans harm the fetus during its development. Currently, there are no known side effects and it is widely accepted that ultrasound scans are a procedure safe for pregnancy. There are no known risks to the baby or the mother from having an ultrasound scan, but you must consider carefully whether to have the scan or not.

  • Why scan in early pregnancy?

    We are specialists in early pregnancy scans. Undergoing an ultrasound scan early in pregnancy not only provides essential health information but also plays a vital role in future decision-making. If the scan reveals any anomalies or concerns, it can be a challenging time for you and your partner. Having this knowledge at an early stage allows you both more time to understand the situation, consider your options, and make informed decisions. It’s a process that requires care, support, and thoughtful consideration, and our team at the clinic is committed to providing compassionate guidance every step of the way. An ultrasound scan in early pregnancy is crucial for several reasons:

    • Confirmation of Pregnancy: It confirms the existence of an intrauterine pregnancy, ensuring the pregnancy is developing in the right place.
    • Establishing Gestational Age: It helps determine the gestational age of the fetus, which is key for calculating the estimated due date.
    • Detection of Multiple Pregnancies: Ultrasound can reveal if you’re expecting twins, triplets, or more, which is important for managing a healthy pregnancy.
    • Assessing Pregnancy Health: It checks the health of the pregnancy, including the heartbeat of the fetus, and can identify potential issues early on.
    • Screening for Chromosomal Abnormalities: Early scans can be part of screening for chromosomal abnormalities like Down syndrome.
    • Reassurance: An early scan provides reassurance, especially for those with a history of miscarriage, IVF, or fertility issues.
    • Planning for Future Care: The information gathered assists healthcare providers in planning appropriate care throughout the pregnancy.

  • Why should I do a private ultrasound scan on top of my NHS scans?

    Choosing to have a private ultrasound scan at the London Pregnancy Clinic, in addition to your NHS scans, offers several benefits that complement your comprehensive pregnancy care:

    1. Early Reassurance: Our private scans can start as early as 10 weeks, providing early reassurance about the health and development of your baby. This early insight reduces the waiting time typically associated with NHS scans.

    2. Comprehensive Anomaly Screening: We offer detailed and comprehensive screening for fetal anomalies. These in-depth scans supplement the standard NHS checks, offering a more thorough examination.

    3. Post-20-Week Scans: After the standard 20-week NHS scan, our clinic provides additional scans to monitor your baby’s position, growth, and overall development. These scans can offer reassurance during the later stages of pregnancy.

    4. Availability of NIPT: Non-Invasive Prenatal Testing (NIPT), a valuable screening for chromosomal abnormalities, is more readily available in our clinic. While the NHS offers NIPT under certain conditions, our clinic provides more accessible options for all expectant mothers.

    5. Flexibility and Personalisation: Private scans offer increased flexibility with appointment scheduling, allowing you to choose the most convenient times and dates. This flexibility ensures that your appointments fit seamlessly into your lifestyle.

    6. Comfortable and Personal Experience: We pride ourselves on creating a patient-centred experience, ensuring each visit is as comfortable and reassuring as possible.

    It’s important to continue with your scheduled NHS scans for a complete overview of your pregnancy’s progress. Private scans at the London Pregnancy Clinic are designed to enhance and complement the care you receive through the NHS, offering additional peace of mind and a more tailored approach to your prenatal care journey.

  • How to prepare for a pregnancy scan?

    Some people think it’s a silly question but we don’t think so! For us preparing for a pregnancy scan is as straightforward as:

    Being Comfortable: Wear loose, comfortable clothing like a top with trousers or a skirt. This choice aids in easy access for abdominal scans and comfort during transvaginal scans. Avoid dresses for pelvic ultrasounds. Instead, choose separates that can be easily adjusted or removed as needed.

    Bringing a Partner: You’re welcome to bring your partner for support during the scan.

Conclusion

Understanding the importance of ultrasound scans demystifies this crucial aspect of prenatal care. It’s more than just a medical procedure; it’s a journey of discovery and connection with your baby.

Innovations in Pregnancy Care

An evening dedicated to LPC’s commitment towards “Innovative Pregnancy Care”

Published

London Pregnancy Clinic’s recent “Innovative Pregnancy Care” event was a confluence of expertise and insight, shaping the future of prenatal care. Leading professionals gathered to discuss breakthroughs in early diagnostics and patient education, emphasising LPC’s forward-thinking approach.

A December evening at Spitalfields Market was transformed into a hub of medical expertise during the London Pregnancy Clinic’s event. The focus was on pioneering approaches in prenatal care, particularly the 10 Week Scan,  Non-invasive prenatal testing (NIPT), and pre-eclampsia diagnosis.

Advancing the 10 Week Scan

The evening began with Ms. Shaz Khojasteh, LPC’s clinical lead, greeting each attendee with a warmth that matched her expertise. Her introduction was not just an opening speech but a heartfelt welcome to LPC’s family. She shared with the audience our signature 10 Week Scan, which isn’t just a routine check. It’s a comprehensive examination of the baby’s anatomy, providing vital developmental insights at a crucial early stage, thereby enriching the information gathered before conducting NIPT.

Demystifying NIPT – Dr Fred Ushakov’s Perspective

The spotlight then shifted to Dr. Fred Ushakov, whose speech was not only insightful but also visionary. He spoke passionately about his mission, in collaboration with the London School of Ultrasound and UCLH, to train the next generation of doctors and sonographers. His goal is to equip them with the skills and knowledge necessary to leverage early pregnancy scans to their full potential, enhancing patient care and pregnancy outcomes. This mission, he explained, is vital in ensuring that every pregnancy is approached with the utmost care and precision.

Dr Ushakov then addressed a common misunderstanding about NIPT. He emphasised that while NIPT is effective, it’s not all-encompassing. Patients may misinterpret it as a guarantee against all prenatal issues, not realising that conditions more severe than Down’s syndrome can occur and cannot be detected by NIPT. He further highlighted the importance of the dual approach (watch the explainer video here) that he instilled at LPC. Dr. Ushakov’s call for broader education and comprehensive scanning techniques underscored the need for a more informed approach to prenatal care.

Advocacy for Pre-eclampsia Awareness

Next, we were captivated by Dr. Daniel Stott, whose talk about pre-eclampsia was as enlightening as it was heartfelt. It was clear from his words and the energy in his voice just how dedicated he is to this topic. Dr. Stott walked us through the workings of a groundbreaking blood test for pre-eclampsia. With an approachable manner, he explained how this test isn’t just for identifying pre-eclampsia; it’s a crucial tool in carefully guiding expectant mothers through the rest of their pregnancy. 

Conclusion

As the expert talks wrapped up, the event naturally transitioned into festive networking. It was a perfect opportunity for attendees to connect, exchange experiences, and build professional ties in a holiday atmosphere. The evening emerged as a crucible of innovative ideas and shared goals for advancing prenatal care. Leaving the market, we carried with us the night’s insights and a renewed hope for the future of prenatal health. The event proved to be not just a confluence of minds but a beacon of hope for prenatal care’s future.

A special thank you to our sponsors Eurofins.

The 10-Week Scan

Answering your questions about the Earliest Anomaly Scan At 10 Weeks

Published

Tags

This blog post discusses the benefits of the 10-week scan, how it is done, and frequently asked questions. It also highlights that the 10-week scan is the best scan to combine with Non-invasive prenatal testing (NIPT), which is a blood test that can be done at 10 weeks to screen for common chromosomal abnormalities. At the London Pregnancy Clinic, We have a unique and individual approach in that we do not ‘leave any stone unturned’ – we provide the most comprehensive assessment of the development of your baby possible at each stage of pregnancy.

Understanding the 10-week Scan:

Typically, the 10-week scan is performed using either a transabdominal or transvaginal ultrasound. A skilled sonographer will place a transducer on your abdomen or within your vagina. This transducer emits sound waves into the uterus, bouncing off the fetus to create a real-time image on the ultrasound screen. The entire procedure generally lasts between 15 to 30 minutes.

Comprehensive Screening:  

In the realm of prenatal care, knowledge is power. The 10-week pregnancy scan, often regarded as the earliest anomaly scan, holds a special place in the hearts of expecting parents. It’s an opportunity to unveil critical insights into your baby’s development, offering early detection of potential fetal anomalies and precise pregnancy dating. This pivotal examination, conducted through either a transabdominal or transvaginal ultrasound, is an indispensable tool in ensuring a smooth and informed journey towards parenthood.

Benefits of the 10-week Scan:  

The advantages of the 10-week scan are numerous and profound:

Early Detection of Fetal Abnormalities: At the 10-week mark, this scan can identify up to 10 major fetal anomalies, providing parents with vital information to make informed choices about their pregnancy.

Accurate Pregnancy Dating: Precise dating of the pregnancy aids parents in planning for their baby’s arrival and arranging future prenatal appointments with confidence.

Reassurance for Parents: Pregnancy is a time of great joy but can also bring anxiety. The 10-week scan offers peace of mind, assuring parents that their pregnancy is progressing as expected.

Optimal Pairing with NIPT: When combined with NIPT, the 10-week scan offers the most accurate information on the baby’s health. NIPT, a blood test conducted at 10 weeks, screens for common chromosomal abnormalities, such as Down syndrome, trisomy 13, and trisomy 18, complementing the 10-week scan perfectly.

IS THE 10-WEEK SCAN FOR ME?

Many pregnant women in the UK are anxious about the health of their babies in the early weeks of pregnancy. This may be due to a number of factors, including:

  • Previous miscarriage
  • IVF pregnancy
  • Unintentional alcohol consumption
  • Missed doses of folic acid
  • Use of certain medications
  • Severe morning sickness
  • Bleeding
  • Unhealthy diet
  • Sudden loss of pregnancy symptoms

If you are concerned about any of these issues or others, our 10-week scan is the perfect solution for you. It is designed to provide early reassurance for expectant parents.

The 10-week scan is also ideal for any pregnant woman who wishes to have NIPT at the earliest possible stage. Many parents choose to screen for the risk of Down syndrome in the first trimester. This is now possible with a non-invasive blood test at 10 weeks. However, the majority of fetal abnormalities are structural (physical), and some of these may be more severe than Down syndrome.

Unfortunately, NIPT will miss all structural abnormalities. That is why we take the opportunity to conduct an early screening of the baby’s structures to rule out 10 major structural abnormalities before performing NIPT.

Should I Delay My NIPT until 12-14 Weeks, Post NHS NT Scan?

Opting to delay your NIPT until after your NHS (National Health Service) Nuchal Translucency (NT) scan at 12-14 weeks is an approach that is becoming increasingly outdated. We firmly believe that the most effective method is to perform both the dating scan at 10 weeks and the NIPT at 10-11 weeks. This approach offers several advantages, particularly regarding early testing.

Admittedly, some fetal structures and organs may not be fully visualized at the 10-week mark, and certain structural anomalies may remain undiagnosed due to the fetus’s ongoing development. However, the benefits of conducting both tests as early as technically feasible outweigh these limitations.

  • IVF pregnancy
  • Unintentional alcohol consumption
  • Missed doses of folic acid
  • Use of certain medications
  • Severe morning sickness
  • Bleeding
  • Unhealthy diet
  • Sudden loss of pregnancy symptoms

If you are concerned about any of these issues or others, our 10-week scan is the perfect solution for you. It is designed to provide early reassurance for expectant parents.

The 10-week scan is also ideal for any pregnant woman who wishes to have NIPT at the earliest possible stage. Many parents choose to screen for the risk of Down syndrome in the first trimester. This is now possible with a non-invasive blood test at 10 weeks. However, the majority of fetal abnormalities are structural (physical), and some of these may be more severe than Down syndrome.

Unfortunately, NIPT will miss all structural abnormalities. That is why we take the opportunity to conduct an early screening of the baby’s structures to rule out 10 major structural abnormalities before performing NIPT.

Your Frequently Asked Questions About 10-week Scan

Do I need a full bladder for the 10-week scan? No, a full bladder is not necessary for the 10-week scan.

What sets the 10-week scan apart from the nuchal translucency scan? In comparison to the nuchal translucency scan, the 10-week scan is more comprehensive. While both can measure the fluid at the back of the baby’s neck, the 10-week scan extends its scope to assess various aspects of the baby’s development, including the heart, brain, and spine.

Is the 10-week scan safe? Yes, the 10-week scan is a safe and well-established procedure. Ultrasound technology has been a trusted method for safely imaging babies in the womb for many years.

Conclusion

If you’re considering delaying your first scan or wish to explore further options, the London Pregnancy Clinic provides innovative Early Ultrasound Screenings. These include the Early Fetal Scan, conducted between 12 and 16 weeks, which can exclude more than one hundred serious anomalies. Moreover, our Early Fetal Echocardiography is designed to identify up to 80% of detectable severe fetal heart defects. We highly recommend this scan for all babies with increased nuchal translucency (NT) measurements, fetal anomalies, or other unusual findings detected at the 11-13 week scan.

In conclusion, the 10-week pregnancy scan is an essential early step in ensuring the health and well-being of your growing family. It empowers parents with valuable insights and peace of mind, setting the stage for a smooth journey into parenthood. And remember, at the London Pregnancy Clinic, we offer a range of pioneering early ultrasound screenings to cater to your specific needs, ensuring the best possible care for your precious one.

Understanding NT’s 95th Percentile:

Nuchal Translucency (NT) Thickness Measurements in the 1st Trimester and What to Do if NT is Increased?

Published

Tags

Nuchal Translucency (NT), developed over 30 years ago in the early 1990s, remains a pivotal screening marker for evaluating early fetal well-being. Widely used, it screens for chromosomal and genetic conditions, as well as heart defects and other structural anomalies in the developing fetus. To get an understanding of NT’s 95th percentile we will discuss the importance of NT measurements, variations in cutoff values, and what to do if your baby’s NT measurement falls above the 95th centile but below the 3.5mm threshold.

The Significance of Nuchal Translucency Measurements:

NT refers to measuring the clear fluid space at the back of the baby’s neck during an ultrasound scan. According to NHS guidelines, it is measured between the 11th and 14th weeks of gestation. Presently, it is a cornerstone of the NHS Chromosomal Syndromes Screening Program conducted through Combined Screening Testing (CST). This program relies on the enduring significance of NT to assess the risk of chromosomal syndromes in the first trimester of pregnancy. Elevated NT measurements can indicate potential chromosomal abnormalities such as trisomy 21 (Down syndrome) and genetic conditions like Noonan syndrome, as well as heart defects and other structural anomalies. However, there is a significant level of uncertainty regarding what constitutes an abnormal NT measurement.

Variations in Cutoff Values:

One of the challenges with NT measurements is determining what constitutes an abnormal measurement. There is considerable variation in the cutoff values used by different research papers and guidelines. The majority of research studies and international society guidelines use the 95th centile as the threshold for abnormal NT measurements. This means that if your baby’s NT measurement falls below the 95th centile, it is considered normal. However, the NHS guidelines use a more conservative cutoff of 3.5mm. This 3.5mm cutoff is equivalent to the 99th percentile, representing a higher threshold for what is considered abnormal by NHS.

The Importance of Gestational Age:

It’s crucial to understand that the 95th centile for NT measurements varies with gestational age. Younger fetuses at 11 weeks tend to have naturally smaller NT measurements compared to those closer to 14 weeks. Therefore, determining whether your baby’s NT measurement is normal or not depends on both the absolute measurement and the gestational age.

Understanding NT’s 95th Percentile Measurements:

We understand that expectant parents might find it challenging to locate validated data concerning the 95th centile cutoff for their baby, as such data is not readily accessible online. To provide support, we have developed an NT thickness reference table based on highly esteemed international data from the study conducted by Wright et al in 20081. Additionally, we have cross-referenced data on normal NT measurements for the 10-11-week gestational period from Grande et al.’s publication in 20142, which closely aligns with Wright’s findings. Consequently, we have assembled a table that delineates the limit of an increased NT (95 centile) for each week from the 10th to the 14th week, utilising gestational age data recommended by the British Medical Ultrasound Society (2009)3.


Gestational Weeks 10+0 10+1 10+2 10+3 10+4 10+5 10+6 11+0 11+1 11+2 11+3 11+4 11+5 11+6 12+0 12+1 12+2 12+3 12+4 12+5 12+6 13+0 13+1 13+2 13+3 13+4 13+5 13+6 14+0 14+1
NT 95th centile mm 2.3 2.3 2.4 2.4 2.4 2.4 2.3 2.2 2.2 2.2 2.2 2.2 2.2 2.2 2.3 2.3 2.4 2.4 2.5 2.6 2.6 2.7 2.7 2.7 2.8 2.8 2.8 2.8 2.8 2.8

Our chart represents the distribution of increased NT measurements (> 95th centile) in relation to the gestational age. It’s important to note that, at every stage of gestation, normal NT measurements remain below 2.8 mm. Therefore, any NT measurement equal to or greater than 2.8 mm is considered elevated.

What occurs when there is a significant elevation in NT measurements? 

If NT thickness is 3.5mm or more (>99th centile) you will be referred to the fetal medicine unit (FMU) of your NHS hospital or FMU of a large regional NHS trust, where doctors will scan your baby to exclude structural anomalies associated with increased NT and offer further tests (CVS or NIPT). They will also offer fetal echocardiography at 16-20 weeks to exclude associated CHD.

What to Do if NT Measurement is Above the 95th Centile but Below 3.5mm (99th centile)?

The NHS adopts a conservative approach and does not acknowledge the 95th centile raised NT cutoff. Consequently, additional scans and tests are not scheduled for these babies before the routine 20-week anomaly scan conducted by the NHS. However, when the NT measurement surpasses the 95th percentile, it is advisable to proceed with further testing. In such instances, considering Non-invasive Prenatal Testing (NIPT) and an Early Fetal Anomaly Scan (Early Fetal Scan) are recommended.

SMART TEST – A Comprehensive Screening Option

For babies with elevated NT (between 95-99th centile), we have introduced the SMART TEST, which stands as the most advanced early reassurance package available. It comprises two expert early anomaly scans, Early Fetal Echocardiography, and the most comprehensive state-of-the-art NIPT panel. The SMART TEST can effectively rule out the majority of severe congenital heart defects (CHDs) and other structural anomalies associated with elevated NT, and reduce the probability of your baby being affected by chromosomal, genetic, or structural abnormalities.

While the SMART TEST is expensive, it is the most comprehensive early reassurance package available in the UK. For parents unable to afford the SMART TEST, there is a more affordable option of the Early Fetal Scan and an extended Panorama Test. The Early Fetal Scan screens for CHDs, but does not include a detailed examination of the fetal heart. You can further upgrade the scan and Panorama Test NIPT package to include eECHO.

If you have received concerning news about your baby’s increased nuchal translucency, we strongly recommend discussing the SMART TEST with one of our specialists.

Conclusion

Nuchal translucency measurements play a crucial role in assessing fetal well-being during the first trimester of pregnancy. Understanding the variations in cutoff values, gestational age, and available screening options is essential for making informed decisions if your baby’s NT measurement falls above the 95th centile but below the 3.5mm NHS threshold (99th centile). The SMART TEST, with its comprehensive NIPT panel and early fetal echocardiography, offers a valuable non-invasive screening option for parents seeking more information about their baby’s health. We are committed to offering you the best possible care, and you are always welcome to have a personal consultation with us to decide on the most suitable approach based on your individual circumstances.

“In 1980, as a young obstetrician heavily involved in attending deliveries and particularly interested in ultrasound technology, I performed a scan on a young pregnant woman. I noticed something unusual about the baby’s brain, although I couldn’t quite discern the exact issue. Subsequently, I was present at her delivery, and to my surprise, the baby was born with spina bifida. This experience was truly shocking. It occurred over 35 years ago during the early stages of ultrasound technology when both knowledge and technology were limited.”

What actions did you take next?

“After that shocking experience, I became genuinely intrigued by effectively detecting spina bifida. I dedicated significant effort to mastering scanning techniques for identifying spina bifida in babies. Over time, I evolved into an expert in this field, with a particular focus on spotting it as early as 10 weeks into the pregnancy. And naturally, I made it a point to share this knowledge with my colleagues, advocating for early spina bifida detection.”

How many babies with spina bifida have you encountered?

“I’ve seen hundreds of fetuses with spina bifida during my career. It’s become a routine part of my work – conducting early scans to detect spina bifida and performing expert scans for babies already diagnosed with this condition. Spina bifida is actually relatively common. In the UK, it’s estimated that around 1 in every 1,000 pregnancies is affected by spina bifida. Even though it might not be as well-known as some other conditions, its effects on those who have it can be quite substantial. This is why early detection and awareness are so important.”

Why is spina bifida so important?

“Open spina bifida holds immense significance due to its prevalence as a major fetal structural defect. It adversely affects essential bodily functions, such as bowel and bladder control. Walking becomes a challenge for most babies born with open spina bifida, and some may also exhibit brain abnormalities. While treatments can enhance outcomes, a complete cure remains elusive. Many babies survive, but their lives are profoundly impacted by long-lasting disabilities. In essence, it’s a severe condition with enduring consequences.”

What do you consider the main issue with spina bifida?

“The primary concern regarding spina bifida, from my perspective, is the alarming lack of awareness. This lack of awareness extends not only to patients but also to primary healthcare providers. From my experience, many pregnant women take folic acid supplements without fully grasping their significance. It’s imperative to raise awareness and educate both the general public and healthcare professionals about this condition, its risk factors, and the crucial role of folic acid supplementation during pregnancy and early first-trimester spina bifida screening. Unlike the widely recognized Down’s syndrome, spina bifida remains relatively obscure. This is a significant concern because, for some babies with spina bifida, the potential outcomes can be even more challenging than those for Down’s syndrome.”

Fred, could you clarify why it’s essential to start taking folic acid immediately upon discovering pregnancy?

“Yes, immediate folic acid supplementation upon discovering pregnancy is of paramount importance. Neural tube formation is an early pregnancy event, usually concluding by the end of the 6th gestational week, approximately 28 days after conception. In babies with spina bifida, the neural tube fails to close correctly, leading to spinal cord and spine bone issues. This anomaly develops extremely early when the baby is less than 1 cm in size and has just initiated its heartbeat.

Folic acid plays a pivotal role during the critical period before and during the first six weeks of pregnancy when the baby’s spine is forming. In practical terms, most people discover their pregnancy around 4 weeks after conception, and by that point, they are already 4 weeks into the pregnancy. This leaves just two weeks during which folic acid can exert its most significant impact. Taking early action is the key to providing essential support for your baby’s neural tube development and minimizing the risk of spina bifida.”

Let’s delve into early Spina Bifida diagnosis during pregnancy. When can you identify this condition?

“With my level of expertise and the use of advanced 3D ultrasound scanners (Fig 1), I can diagnose the majority, probably over 90%, of open spina bifida as early as 10 weeks into the pregnancy. To put it differently, personally missing a diagnosis of spina bifida at that stage would be a great disappointment to me, and I would be highly motivated to conduct a thorough investigation into why such a diagnosis was missed.

  • It’s important to note that achieving a 100% accuracy rate in diagnosing spina bifida through ultrasound is a challenge. There can be significant variations in the presentation of spina bifida, and in some rare cases, the anomaly may go undiagnosed until delivery. While early detection is highly valuable, there are instances where the condition’s subtleties make it difficult to diagnose definitively with ultrasound.”

How can you diagnose spina bifida so early? Are you inspecting the baby’s spine?

“No, actually, it’s quite challenging to directly visualize spinal abnormalities at this early stage. What I’m primarily focused on is the fetal head and brain (Fig 2). In cases of open spina bifida, there’s a distinct phenomenon at play. There is a leakage of fluid from the brain through the hole in the spine, and this leakage creates a very specific brain anomaly known as Chiari 2 malformation. I’m essentially searching for the earliest evidence of this phenomenon in the ultrasound images. It’s a highly specific indicator – when this particular brain anomaly is present, it’s a strong indication that the baby has spina bifida.

Certainly, at 10 weeks, I also examine the fetal spine. The spine is not yet ossified, so it appears as dark lines running along the baby’s back, and often I can even discern individual vertebrae as bright dots (Fig 3). This level of detail means that very severe spinal deformities can be visible. Sometimes, spina bifida can manifest as a small bubble on the baby’s back at this early stage (Fig 4).”

Can other professionals detect spina bifida early?

“Yes, there are indeed many research studies indicating the possibility of early detection. One of the most significant research efforts comes from King’s College Hospital in London. Sonographers at this hospital have scanned over 100,000 babies at 11-13 weeks of pregnancy and were able to detect more than half of the fetuses with spina bifida. This achievement is truly impressive, although it’s important to note that it may not be applicable to all NHS trusts. King’s College Hospital has a dedicated unit, established protocols, and a comprehensive training program. Only a handful of other hospitals across the UK, including UCLH that I work for, have similar protocols in place.”

What is the situation like in an average NHS hospital?

“In NHS hospitals, there is a screening ultrasound program called the anomaly scan, which is typically conducted at 19-20 weeks into the pregnancy. During this scan, sonographers check for spina bifida among other anomalies.

Unfortunately, there isn’t a routine first-trimester screening for spina bifida, and the majority of cases are detected during the second trimester. In a 2019 survey of ultrasound units performing scans in the first trimester (11-13 weeks) in England, it was found that only 16% of them included a check of the fetal spine in their protocols.”

Tell us about the “crash sign” and its significance.

“Yes, indeed. Many research groups have proposed various methods for detecting spina bifida in the first trimester. In our case, we’ve come up with a marker that represents the ultrasound appearance of Chiari 2 malformation in the early fetal brain. It’s pretty obvious when you have a top-notch ultrasound scanner.

Now, why ‘CRASH’? We actually have a video up on YouTube that demonstrates it, and once you watch it, the name will make perfect sense.”

Any advice for patients seeking early spina bifida ruling out?

“If you’re keen to know early on, I’d suggest considering booking a 10 Week Scan with a professional having a special interest in this area. For those with previous pregnancies affected by spina bifida, arranging a 10 Week Scan at Fetal Medicine Unit at UCLH with a referral from your primary NHS care provider is an excellent choice. Alternatively, you can book a 10 Week Scan privately at London Pregnancy Clinic. At our clinic, we can combine this scan with non-invasive prenatal testing (NIPT). Please inform our admin staff about your worries, and we will arrange a proper scan for your baby.

If you prefer to stick with NHS services, ask your sonographer during the 11-13 weeks scan if they’re actively screening for spina bifida. Some hospitals in London may have established protocols for this. However, if your NHS provider doesn’t routinely check for spina bifida (which is the case for most hospitals), you might want to consider an early anomaly scan (Early Fetal Scan) at 13-16 weeks through a private provider. For those going the private scan route, it’s a good idea to check if the clinic screens for spina bifida at early stages. Advanced private ultrasound clinics are typically well-equipped, and their staff may have special training in fetal medicine.

Please note that the majority of sonographer-run clinics that provide NIPT or perform non-medical gender scans do not screen for spina bifida.”

It seems like you prefer screening for spina bifida at 10 weeks rather than at the time of the standard NHS scan around 12 weeks. Is that accurate, and could you tell us why?

“Yes, you’ve got it right. In the past, I used to advocate for spina bifida screening during the conventional nuchal translucency scan at around 12-13 weeks. But with the introduction of NIPT, which can be done as early as 10 weeks, I’ve started scanning for spina bifida even before the blood test. At 10 weeks, the little ones are really tiny, measuring less than 1.5 inches (around 35 mm).

Interestingly, with the help of state-of-the-art ultrasound technology (and we’re lucky to use the most advanced machines), many fetal structures are surprisingly easier to examine at 10 weeks compared to 12 weeks. The brain and spine, in particular, stand out as more visible structures.

I won’t bore you with all the technical stuff, but it’s somewhat paradoxical that I feel that an early screening at 10 weeks is actually probably more effective. Plus, it’s a relief for parents who are understandably anxious and want reassurance as soon as possible. But it’s essential to recognize that this type of screening demands a high level of expertise and top-notch ultrasound technology to be done effectively.”

Can other professionals detect spina bifida early?

“Yes, indeed. There are internationally renowned groups in Melbourne, Nice, and Berlin, among others, who also have experience in diagnosing spina bifida before the 11th week of pregnancy. At present, our joined expertise is largely based on anecdotal cases. This is because the incidence of spina bifida is relatively rare, occurring at a rate of 1 in 1,000 pregnancies. To establish statistically significant numbers and determine the detection rate of a 10-week scan, one would need to scan thousands and thousands of babies.”

What is the SMART TEST, and does it include screening for spina bifida?

“The SMART TEST is an innovative concept in prenatal care developed and offered by the London Pregnancy Clinic. It combines extended NIPT with expert ultrasound. The SMART TEST is unique in that it covers a wide range of structural anomalies, chromosomal conditions, and genetic diseases, and it can do so as early as 10 weeks into the pregnancy.

A primary target of the SMART TEST is indeed the earliest possible screening for spina bifida. The test incorporates advanced 2D and 3D ultrasound technology to thoroughly examine the fetal brain and spine at a stage when the baby has just transitioned from an embryo to a fetus. This comprehensive approach ensures early detection and peace of mind for expectant parents.”

Why do you believe that early detection of spina bifida is so crucial? After all, the condition can be diagnosed by the NHS anomaly scan at 20 weeks.

“I’m a strong advocate for early detection of spina bifida, and let me explain why. Spina bifida is a highly serious structural anomaly associated with severe disabilities. While we’ve made significant progress with in-utero surgical treatments, it’s important to understand that these treatments don’t cure the condition.

Moreover, it’s essential to highlight the significance of the surgical aspect. At UCLH, I’m part of the Fetal Surgery for Spina Bifida team, which is led by Professor Jan Deprest, an internationally renowned expert in fetal surgery. Our centre is the sole one in the UK commissioned by the NHS to provide this cutting-edge treatment. In my role, I conduct scans on the baby before and after the surgery. I take great care to evaluate the spinal lesion, perform a thorough examination of the baby’s brain, and perform a comprehensive top-to-toe scan of the entire baby. I’ve had the privilege of scanning hundreds of babies with spina bifida before and after surgery, contributing to their care.

Performing surgery on a baby with spina bifida while they’re still in the mother’s womb is an incredible feat. This complex procedure requires a skilled international team of doctors and medical professionals from the UK and Belgium. The delicate balance of providing life-changing treatment for the baby while ensuring the safety of both the baby and the mother is a remarkable achievement in fetal medicine.

However, almost half of mothers are not eligible for this ground-breaking surgical treatment, often due to the severity of the baby’s condition or additional fetal problems. For these parents, making difficult decisions about the pregnancy becomes a reality, often after 20 weeks. Even for parents eligible for surgery, the journey is challenging. They go through numerous tests, counselling, and procedures in a short time, adding to the stress.

All of this can be alleviated with early diagnosis. Early detection provides parents with the time and information they need to make informed decisions. For the most severe cases of spina bifida that are not operable, early detection helps parents understand their options from the start of the pregnancy. That’s why I advocate for screening for spina bifida as early as 10 weeks or at least at 12 weeks.”

Fred, as a conclusion, what advice or suggestions would you like to offer to future parents?

“If you are in the planning stages of pregnancy, consider starting to take folic acid supplements. Folic acid is most effective when taken before conception and during the first few weeks of pregnancy when the baby’s spine is forming. This simple step can contribute to the healthy development of your baby and reduce the risk of spina bifida.

Additionally, I’d like to emphasize the importance of early screening for spina bifida, which can now be done as early as 10 weeks into the pregnancy. This can provide you with valuable information, peace of mind, and ample time to make informed decisions about your baby’s health. If you have concerns or a history of spina bifida in your family, consider the SMART TEST at the London Pregnancy Clinic. It’s a comprehensive approach that combines NIPT and advanced ultrasound technology to screen for a wide range of conditions, including spina bifida.

Remember that knowledge is power. Being informed and seeking early detection can make a significant difference in the journey of your pregnancy. Stay well-informed, ask questions, and don’t hesitate to seek expert guidance. Your baby’s health is our priority, and we are here to help you every step of the way.”

Spina Bifida Awareness Week:

What is it? and how we can screen for it?

Published

This week is Spina Bifida Awareness Week, a time to shine a light on this important condition. We look at what Spina Bifida is, how it can be detected and charities that spread awareness about it.

Comprehensive Screening:  

From the 16th to the 22nd of October, we shine a light on Spina Bifida Awareness Week. But first, let’s break it down. What exactly is spina bifida? It’s a condition where the spine doesn’t fully develop in the womb. It occurs when the spine and spinal cord fail to develop properly in the womb, resulting in a gap in the spine. This incomplete development can lead to both physical and intellectual challenges.

A surprising fact? As many as 10% of people might have a milder form of spina bifida. Most aren’t even aware of it. On the more severe end of the spectrum, open spina bifida impacts about 700 babies in the UK every year.

Now, here’s the uplifting part. Taking folic acid during the early stages of pregnancy can significantly reduce the risk of a baby developing spina bifida. However, many women still don’t know about this simple preventative measure. It’s essential for healthcare providers to share this knowledge.

Early Detection Makes a Difference! 

At our clinic, we’re proud to offer a specialised Ten-week Anomaly Scan. This scan is designed to detect signs of spina bifida at a very early stage. By identifying it early, families can make informed decisions and medical professionals can provide the best care options. Early detection can dramatically improve outcomes for affected pregnancies. Surgeons from UCLH and GOSH carried out the first procedure on babies in the womb in the UK back in 2018. This international team received their training at UZ Leuven1

While many might be more familiar with conditions like Down Syndrome, it’s vital to bring spina bifida to the forefront as well. Its prevalence is notable, and with the right measures like early detection and folic acid intake, we can make a difference.

Join Our Mission in Boosting Awareness: 

Knowledge is power. By understanding spina bifida, its risks, and the preventive steps, we can safeguard future generations. Let’s raise the bar of awareness together by educating ourselves and supporting charities like Shine. 

Shine Charity is a UK-based charity that supports people with spina bifida and hydrocephalus. The charity’s vision is a society where all those affected by spina bifida and/or hydrocephalus are empowered and enabled. Shine’s mission is to make a positive difference to the lives of people affected by these conditions.

Shine’s goals for 2022-2027 include:

  • Enabling babies and children with spina bifida and/or hydrocephalus to achieve their potential
  • Empowering young people with these conditions
  • Ensuring that adults with these conditions have the choices and opportunities to live healthy and independent lives

NIPT and Scan Approach: Why We Champion This Screening Method at London Pregnancy Clinic

At the London Pregnancy Clinic, we’re dedicated to providing expectant mothers with advanced screening options and the highest level of care. We firmly recommend combining Non-Invasive Prenatal Testing (NIPT) and Ultrasound screening. Let’s explore why we endorse NIPT and Scan approach and how it benefits our patients.

Why Choose Both NIPT and scan?

Comprehensive Screening:  

Ultrasound visually assesses the baby’s anatomy, checking for physical abnormalities and measuring growth. NIPT, known by brand names like Natera’s Panorama AI or Eurofins’ PrenatalSafe, examines fetal DNA in the mother’s bloodstream, providing insights into potential chromosomal abnormalities like Down’s Syndrome, Edwards syndrome, and Patau syndrome.

Increased Accuracy and Early Detection:  

By merging Ultrasound’s structural insights with genetic data from NIPT, we significantly reduce false positives and offer more accurate results. As early as 10 weeks, when your baby is the size of a strawberry, we initiate the dual screening process. At this stage, we conduct the earliest possible structural anomaly scan, the Ten-week Anomaly Scan, to search for structural anomalies that NIPT can’t detect. We can rule out severe physical abnormalities like Acrania, Spina bifida, Absence of arms, hands, legs or feet, and Alobar holoprosencephaly. Only after confirming your baby’s structural development do we proceed with the NIPT test.

UNDERSTANDING THE TECHNOLOGY

Ultrasound Screening: 

Ultrasound employs sound waves to create images of the baby in the womb. A small probe, called a transducer, moves over the mother’s abdomen. The transducer emits high-frequency sound waves that bounce off the baby’s structures, and these echoes are converted into images on a screen.

Non-Invasive Prenatal Testing (NIPT): 

NIPT is a simple blood test taken from the expectant mother. This test detects tiny fragments of the baby’s DNA circulating in the mother’s bloodstream. By analysing these fragments, we can determine the risk of certain chromosomal conditions.

Is It Safe?

Absolutely. Both Ultrasound and NIPT are non-invasive and pose minimal to no risk to both mother and baby. However, it’s important to note that while NIPT is highly effective, it’s not a definitive diagnostic test. In cases of low negative predictive value, our doctors may recommend invasive tests like CVS or amniocentesis, which carry minimal miscarriage risk.

Additionally, our Early Fetal Echocardiography is designed to identify up to 80% of detectable severe fetal heart defects. It is a scan we highly recommend this scan for all babies with increased nuchal translucency (NT) measurements, fetal anomalies, or other unusual findings detected at 11-13 weeks scan.

Conclusion

At the London Pregnancy Clinic, we believe in providing the most comprehensive care possible. By endorsing the dual Ultrasound and NIPT approach, we ensure that our patients receive a detailed, accurate, and safe assessment of their baby’s health. Whether you choose the ten-week scan or another early anomaly scan, we’re here to guide and support you every step of the way.
