NT/NB Scan in New Delhi – Early Pregnancy Screening for Your Baby’s Healthy Development
An NT/NB Scan (Nuchal Translucency and Nasal Bone Scan) is an important first-trimester ultrasound performed to assess your baby’s early development and screen for the risk of certain chromosomal conditions. This specialized scan measures the fluid at the back of the baby’s neck (nuchal translucency) and evaluates the presence of the nasal bone. When combined with maternal blood tests and other clinical assessments, it helps doctors estimate the likelihood of specific genetic conditions while providing valuable information about the baby’s overall well-being.

What is an NT/NB Scan?
An NT/NB Scan is a specialized ultrasound examination performed during the first trimester of pregnancy, usually between 11 and 13 weeks plus 6 days of gestation. The scan measures the thickness of the fluid-filled space at the back of the baby’s neck, known as the nuchal translucency (NT), and checks whether the nasal bone (NB) is visible.
These findings are combined with the mother’s age, pregnancy history, and, when recommended, blood test results to estimate the risk of certain chromosomal abnormalities. The scan also evaluates the baby’s heartbeat, growth, and early anatomy, making it an important part of routine prenatal care.
Why is an NT/NB Scan Important?
An NT/NB Scan helps identify pregnancies that may require additional evaluation while providing reassurance when the baby’s early development appears normal.
Key benefits include:
Early screening for chromosomal abnormalities
Accurate assessment of nuchal translucency
Evaluation of the baby’s nasal bone
Confirmation of fetal heartbeat
Assessment of early fetal growth
Accurate pregnancy dating
Early evaluation of fetal anatomy
Support for informed pregnancy management
Greater reassurance for expecting parents
Early prenatal screening allows doctors to recommend additional testing only when necessary.
What Happens During an NT/NB Scan?
An NT/NB Scan is a safe, painless, and non-invasive ultrasound examination performed through the mother’s abdomen. In some early pregnancies, a transvaginal ultrasound may be recommended to obtain clearer images.
During the scan, the doctor may evaluate:
Nuchal translucency measurement
Presence of the nasal bone
Baby’s heartbeat
Crown-rump length (CRL)
Gestational age
Early fetal anatomy
Number of babies
Placental position
Overall fetal development
The scan usually takes around 20 to 30 minutes, depending on the baby’s position and the quality of the images obtained.
