A Nuchal Translucency Ultrasound is a specialized prenatal screening exam used to help identify higher chances of chromosomal conditions (such as Down’s syndrome) during fetal development. During this routine exam a specially trained and certified Diagnostic Sonographer measures a collection of fluid under the skin behind the fetal neck during the first-trimester of pregnancy. All babies have some fluid in this area, but babies with an increased amount of fluid are at an increased risk of chromosomal conditions.
This exam is very similar to other prenatal ultrasounds that you may have where measurements of your baby are taken to measure fetal development. As with all other types of Ultrasound, a Nuchal Translucency exam is safe and painless. Because ultrasound images are captured in real-time, they can show the structure and movement of the body’s internal organs, as well as blood flowing through blood vessels. Ultrasound is a useful way of examining many of the body’s internal organs, along with fetal development during pregnancy.
There is a limited period of time during the pregnancy (between 11 weeks and 13 weeks-plus-six-days) when a Nuchal Translucency Ultrasound can be performed. Any earlier in the pregnancy and the baby is too small for accurate measurements and any later in the pregnancy and excess fluid in the neck is naturally absorbed by the fetus.
