Nuchal translucency is the ultrasound analysis of a fetus in the first trimester of pregnancy. This procedure looks at a collection of fluid under the skin behind the neck of fetuses (the nuchal fold) at 11-14 weeks that can be measured by ultrasound examination. In fetuses with chromosomal abnormalities, cardiac defects and many genetic syndromes, nuchal translucency is increased (>3.5mm), and research suggests that the likelihood of anomaly correlates with this measurement, maternal serum screening (MSS), and maternal age.
