nuchal screening scan - SPORTS
A nuchal scan or nuchal translucency (NT) scan / procedure is a sonographic prenatal screening scan (ultrasound) to detect chromosomal abnormalities in a fetus, though altered extracellular matrix composition and limited lymphatic drainage can also be detected. If you’re pregnant, your doctor might have mentioned an NT scan or first-trimester screening. An NT scan is a simple test that shows your baby’s risk for some genetic conditions.

Nuchal (“NEW-kuhl”) translucency (NT) is a type of prenatal ultrasound that measures the amount of fluid behind the fetus’s neck in the first trimester of pregnancy. The fluid underneath the skin along the back of the fetus’s neck, called the nuchal translucency, or nuchal fold. In some pregnancies, when the fetus has Down syndrome, trisomy 13 or trisomy 18, there is extra fluid behind the neck. The term “nuchal” is a medical and anatomical descriptor used to identify structures or conditions associated with a specific area of the body.
