Hello,
Welcome to the ehealthforum and I am glad to help you.

Nuchal translucency is a collection of fluid under the skin at the back of a baby's neck. The nuchal translucency scan measures the thickness of this fluid to assess the risk of Down's syndrome.

If the scan reveals that there is more fluid than usual, it could be a sign of Down's syndrome. Another sign of Down's syndrome is the shape of the baby's nasal bone. In your case, the nasal bone appears ok.

A nuchal translucency scan can only indicate the level of risk of your baby having Down's syndrome. To get a definitive diagnosis, a test such as amniocentesis is necessary.

This test also carries a small risk of miscarriage though so your doctor will only suggest them if there is a high risk of Down's. The nuchal translucency scan is usually advised in first time pregnancies, high-risk pregnancies and in pregnant women who are over 35 years of age.

In your case, it appears ok and the risk of Down’s syndrome seems less likely. I sincerely hope that helps. Take care.
