NT Scan at AV Scan Diagnostics, Dadar West

The NT scan (nuchal translucency scan) is a time-sensitive first-trimester ultrasound that screens for chromosomal conditions, including Down syndrome. At AV Scan, all NT scans are performed to FMF (UK) protocol, an internationally standardised method, on the GE Voluson E10 ultrasound system.

Both our radiologists hold FMF (UK) certification for NT scanning, which involves theory training, assessment of submitted scan images and annual audit of NT measurements. This means the NT is measured by a standardised method that is checked through regular audit.

Important: The NT scan must be performed between 11 weeks 0 days and 13 weeks 6 days of pregnancy. This window is strict — book your appointment early to ensure you don't miss it.

What Does the NT Scan Measure?

The NT scan measures the fluid at the back of the baby's neck (nuchal translucency). When combined with maternal blood tests (PAPP-A and free beta-hCG), it calculates individual risk for:

  • Trisomy 21 (Down syndrome), the most common of the three conditions screened for
  • Trisomy 18 (Edwards syndrome)
  • Trisomy 13 (Patau syndrome)

What Else Is Assessed at the NT Scan?

  • Nasal bone: if it is not seen, the chance of Down syndrome is higher, although many healthy babies also have no visible nasal bone at this stage
  • Fetal heart rate
  • Ductus venosus blood flow, where indicated
  • Blood flow across the tricuspid valve, where indicated
  • Accurate gestational age and due date (CRL measurement)
  • Number of fetuses (twins, triplets)
  • Early structural assessment of fetal anatomy
  • Uterus, ovaries and, where indicated, cervical length

How to Prepare for Your NT Scan

  • Book your appointment early — the window is strictly 11w0d to 13w6d
  • Have a moderately full bladder (drink 2–3 glasses of water 30 minutes before)
  • Bring your antenatal blood test results if available
  • Bring your first trimester ultrasound report (if done elsewhere)
  • Scan time: usually about 30–45 minutes, longer if the baby needs time to move into position
  • Our team confirms the exact preparation when you book on WhatsApp

What Happens at Your NT Scan Visit

Your NT scan is performed by the radiologist who reports it. Both our radiologists are FMF (UK) certified. A typical visit to our Dadar West centre goes like this:

  • Check-in: our team notes the first day of your last period (or, after IVF, your embryo transfer date), your doctor's prescription and any earlier scan reports. We also note a few details the risk calculation uses, such as your weight, whether you conceived through IVF and whether an earlier pregnancy had a chromosomal condition.
  • The scan: you lie on your back and the scan is done over the tummy. If the view is not clear, an internal (transvaginal) scan may be suggested. It is safe in pregnancy, it is done only with your consent, and you can ask to stop at any time.
  • The measurement: the NT can only be measured when the baby lies in the right position, with the head in line with the body. If the baby is curled up or facing away, we may ask you to walk around for a while and come back to the scan room. Occasionally a repeat visit is needed, which is why booking early in the 11 to 13+6 week window helps.
  • The dual marker sample: if your doctor has asked for combined screening, the blood sample can be given at our centre before you leave. It is processed by our partner laboratory.
  • Before you leave: the radiologist explains what was seen, including the heartbeat, the number of babies, the dating of the pregnancy and the NT measurement.
  • Your report: most reports are ready the same day and sent to your WhatsApp. If you have the dual marker test, the combined risk follows once the blood result is available, and our team tells you when to expect it.

The visit usually takes about 30–45 minutes, and longer if the baby needs time to move. If you have heavy bleeding or severe tummy pain, or you feel faint, do not wait for your scan appointment. Go to a hospital emergency department first.

First Trimester Combined Screening

The NT scan is more precise as a screening test when it is combined with a first-trimester blood test, the dual marker (PAPP-A and free beta-hCG). At AV Scan, the dual marker blood sample can usually be given at our centre on the same visit as your scan, and is processed by our partner laboratory. Ask us about this when you book.

What Your NT Scan Result Means

The NT scan with the dual marker test is a screening test, not a diagnosis. It does not tell you whether your baby has a chromosomal condition. It estimates the chance (risk) that your baby has Down syndrome (trisomy 21), Edwards syndrome (trisomy 18) or Patau syndrome (trisomy 13).

Keep your NT scan report and bring it to your anomaly scan and growth scans, so later findings can be compared with it.

Frequently Asked Questions

The NT scan must be done between 11 weeks 0 days and 13 weeks 6 days of pregnancy — this window is strict. We recommend booking as soon as you have your dating scan. Call or WhatsApp us at +91 98200 51511.
An increased NT measurement does not mean your baby definitely has a chromosomal condition — it increases the risk that needs further evaluation. The radiologist will explain the scan findings to you, and your doctor will discuss the next steps with you.
No. The NT scan is a standard ultrasound over the tummy and uses no radiation. A full bladder or the pressure of the probe may feel slightly uncomfortable. In some cases, an internal (transvaginal) scan may be needed if the view over the tummy is not clear. It is safe in pregnancy and is done only with your consent.
A moderately full bladder helps with the abdominal view in early pregnancy. Drink 2–3 glasses of water about 30 minutes before your appointment. Our team confirms the exact preparation when you book on WhatsApp.
The FMF (Fetal Medicine Foundation, UK) protocol is an internationally recognised standard for NT scanning. It sets strict criteria for the image, for how the measurement is taken and for the baby's size at the time of the scan (crown-rump length 45–84 mm), and practitioners must be certified and have their measurements audited. Both our radiologists hold current FMF (UK) certification.
Usually not. The NT scan is often called the 11–14 week scan, but the measurement is valid only up to 13 weeks 6 days, while the baby measures no more than 84 mm from head to bottom (crown-rump length). If you are already past this window, the NT measurement cannot be used for screening. Your doctor will discuss other screening options with you, and the anomaly (TIFFA) scan at 18–22 weeks still checks the baby in detail. Book early so that your scan falls comfortably inside the window.
It can be. The dual marker is a blood test that measures two pregnancy hormones, PAPP-A and free beta-hCG. For combined screening, the sample must be taken before the end of 13 weeks 6 days, so giving it on the same visit is usually simplest. At AV Scan in Dadar West, the sample can usually be given at our centre on the same visit as your NT scan, and it is processed by our partner laboratory. No fasting is usually needed. Combining the blood result with the NT measurement and your age gives a more precise risk than the scan alone. Our team confirms the exact preparation when you book on WhatsApp.
There is no single normal number, because the NT normally increases slightly as the baby grows between 11 and 13+6 weeks. The measurement is judged against the baby's size (crown-rump length) and combined with your age and, if done, the dual marker result to give a risk. As a general guide, an NT of 3.5 mm or more is above the expected range at any point in the window, and a smaller measurement can also be above the expected range for a smaller baby. An increased NT is not a diagnosis. Even when the chromosomes are normal, an increased NT can be linked with heart and other conditions, so your doctor may advise a detailed heart scan (fetal echo) and a detailed anomaly scan later in pregnancy. Our radiologist explains the findings, and your doctor will discuss the next steps with you.
The cost of an NT scan usually depends on what is included, such as whether the dual marker blood test is added for combined screening, whether it is a twin pregnancy, and whether your doctor has asked for any additional checks. At AV Scan Diagnostics in Dadar West / Prabhadevi, the exact price is confirmed on WhatsApp before your visit. Send your doctor's prescription to +91 98200 51511.
Useful things to check: whether the doctor who scans you holds FMF (UK) certification for the NT scan, since the risk calculation depends on a standardised measurement; whether the same doctor who scans you also writes the report; whether the dual marker blood test can be arranged for combined screening; and whether the result is explained to you. At AV Scan Diagnostics in Dadar West / Prabhadevi, near Siddhivinayak Temple, NT scans are performed and reported by our FMF (UK) certified radiologists on a GE Voluson E10. The dual marker sample is collected at the centre, and most reports are sent to your WhatsApp the same day.
Yes. In twins, the NT is measured for each baby separately. The scan also shows whether the twins share a placenta, which is most reliably seen in the first trimester and guides how closely the pregnancy is monitored. In twins, the blood test gives one combined result for both babies, so it is adjusted for twins, and each baby's risk relies more on its own scan measurements. After IVF, tell us that the pregnancy was conceived through IVF, your embryo transfer date, and the egg donor's age if a donor egg was used, because the risk calculation uses them. Our team confirms the details when you book on WhatsApp.
