Common "Nt Scan" queries answered by top doctors | iCliniq

Nt Scan

An NT (Nuchal Translucency) scan is a prenatal screening done in the first trimester, which measures the size of the clear tissue at the back of the fetus's neck called the nuchal translucency. Too much clear space indicates chromosomal abnormalities like Down syndrome, Patau syndrome or Edwards syndrome.
