Nuchal Translucency (NT) Scan
What is Nuchal Translucency (NT) Scan?
Nuchal Translucency or NT scan, is a pregnancy screening test in which the thickness of a fluid collection at the back of the baby’s neck is measured. Genetic problems in the fetus like Down’s syndrome can be suspected with the help of this test. Generally performed between 11 to 13 weeks 6 days of pregnancy, it is a screening test for chromosomal anomalies. Few congenital heart diseases are also associated with increased NT.
Time taken for the procedure is generally 30 to 45 minutes. Rarely repeated sittings are needed to get the baby in the correct position for these measurements. The position of the baby is very important to avoid false-positive and false-negative results. An abdominal, as well as a vaginal scan, may be required at times to study the baby in detail.
