Nuchal Translucency (NT) Scan
What is a Nuchal Translucency Scan?
Nuchal translucency scan is a part of the ultrasound scan. Performed around the 12th week of pregnancy, the scan aims to measure the size of the nuchal fold at the back of the baby’s neck in order to rule out the possibility or risk of any chromosomal abnormalities.
It rules out risk of abnormalities like trisomy 21 (Down Syndrome), trisomy 18 (Edwards Syndrome) or trisomy 13 (Patau syndrome). But remember that this scanning technique is used only for detecting the risk (high or low). A positive result is not a definitive answer.
How is it done?
The NT scan may be combined with other tests and scans in the 11th and 14th week of pregnancy. The ultrasound scan is transvaginal (inserting a probe into the vagina) or transabdominal (through your abdomen). Once the images are created, the doctor measures the nuchal translucency or the clear space at the back of the foetus’s neck to calculate if there are risks of chromosomal abnormalities.
The NT scan is often coupled with a blood test to get a clearer and more accurate picture of the risk of chromosomal abnormalites.
