Translucency Scanning – Assessing the Likelihood of Down’s Syndrome
A nuchal translucency scan is used to help identify possible chromosomal conditions such as Down’s syndrome in pregnancy.
Nuchal translucency is a collection of fluid under the skin at the back of your baby's neck that can be measured using ultrasound scanning. A nuchal scan (often referred to as a NT Procedure), can only estimate the risk of your baby having Down’s syndrome, giving you statistical information that will determine the likelihood. For example, if your result is one in 1000, this means that for every 1000 babies born with the same level of risk, one will have Down’s syndrome.
Women who are older are at higher risk when it comes to Down’s syndrome and often consider the nuchal scan to identify any issues. The scan is carried out from 11-14 weeks.
During the nuchal translucency scan, two measurements are taken; the nuchal translucency and the nuchal fold, with the focus being on the quantity of fluid collecting within the nape of the fetal neck. Fetuses with Down’s syndrome tend to have an increased amount of fluid around the neck.
Additional factors such as fetus CRL (Crown Rump Length), nuchal translucency, the mother’s age, height and weight are all considered when assessing the risk of Down’s syndrome. The nuchal scan will also assess the fetal heartbeat, identify the basic anatomy and give an ultrasound due date.
You may also opt for a combined nuchal translucency scan which includes a blood test to increase the sensitivity of the results, as recommended by the Fetal Anomaly Screening Program (FASP).
