What is an NT Scan?
An NT (Nuchal Translucency) Scan is a specialized ultrasound performed in the first trimester. It measures the clear (translucent) space in the tissue at the back of your baby's neck. All babies have some fluid here, but babies with chromosomal abnormalities (like Down syndrome, Trisomy 18, or Trisomy 13) or major structural defects tend to accumulate more fluid.
When is the best time for an NT Scan in Kollam?
Strictly between 11 weeks 0 days to 13 weeks 6 days. Ideally schedule between 12 to 13 weeks for the best visibility. Missing this window means the opportunity is gone.
What Does an NT Scan Detect?
While often described as a Down syndrome screening test, the NT scan is a comprehensive early structural survey. It helps detect:
- Risk for chromosomal abnormalities (Down syndrome, Edwards syndrome, Patau syndrome)
- Early detection of major structural defects (brain, spine, abdomen, heart)
- Early suspicion of congenital heart defects (nasal bone, ductus venosus assessment)
- Accurate dating of pregnancy by crown-rump length (CRL)
- Diagnosis of multiple pregnancies and chorionicity (critical for twin management)
