Nuchal Translucency & Nasal Bone Scan
The NT-NB scan is usually performed between 11 and 13 weeks of pregnancy. It measures the nuchal translucency (fluid behind the baby’s neck) and checks the presence of the nasal bone. Together, these markers help assess the risk of chromosomal conditions such as Down syndrome.

Ensuring Safe beginnings for a healthy family.
Dr Sweta Bothra, Siliguri performs NT-NB scans with precise measurements and careful evaluation. The scan is often combined with blood tests as part of first trimester screening to provide a more complete risk assessment.
This scan helps in:
Results are explained clearly, along with guidance on whether further screening or tests are needed.
The scan is done between 11 weeks and 13 weeks 6 days of pregnancy for accurate assessment.
While not compulsory, it is strongly recommended as part of first trimester screening for early risk assessment.
No. An increased NT only indicates higher risk, not a diagnosis. Further tests may be advised for clarity.
No. It is a simple ultrasound scan and completely safe for both mother and baby.
No. It is a screening test for chromosomal risk. Structural abnormalities are assessed in detail during the anatomy scan later in pregnancy.
Based on results, routine follow-up, blood tests, or additional screening may be advised. Everything is discussed clearly before any decision.
