Nuchal translucency (NT) or nuchal fold is an accumulation of fluid seen by ultrasound under the skin at the nape of the fetus' neck, i.e. at the back of the neck.
The thickness of the nuchal translucency is the best ultrasound marker of fetal aneuploidy, especially trisomy 21, which gives rise to Down syndrome.
The NT should be less than 3 mm to consider that the baby has no problem. On the other hand, if the NT is greater than 3 mm, it indicates that the baby is at risk of suffering from a chromosomal disorder, so more prenatal tests should be performed.
