Q. What is a nuchal translucency (NT) scan, and why is it performed during pregnancy? A. The NT scan is a non-invasive prenatal screening procedure that measures the translucent space at the back of the baby's neck to assess the risk of chromosomal abnormalities, such as Down syndrome, Edwards syndrome, and Patau syndrome. It also helps identify congenital heart defects.
Q. At what stage of pregnancy is the nuchal translucency scan typically performed? A. The NT scan is usually performed between the 11th and 14th weeks of pregnancy. This timeframe is optimal for accurate measurements and reliable results.
Q. What does the nuchal translucency scan procedure involve? A. The procedure involves a standard ultrasound examination where a transducer is moved over the mother's abdomen to measure the nuchal translucency, record the fetal heart rate, and gather information about the baby's anatomy. A blood test measuring specific hormones may also be conducted to enhance screening accuracy.
Q. Is the nuchal translucency scan safe for both the mother and the baby? A. Yes, the NT scan is considered safe. It is a non-invasive procedure that uses ultrasound technology, which has been widely used in pregnancy and has a good safety record. There is no radiation involved.
Q. What do the results of the nuchal translucency scan indicate? A. The results are usually given as a combined risk factor, considering maternal age, nuchal translucency measurement, and blood test results. A low-risk result suggests a lower likelihood of chromosomal abnormalities, while a high-risk result indicates an increased likelihood of requiring further diagnostic tests for confirmation.
