12 Weeks Nuchal Ultrasound Scan
Introduction
Nuchal NT Scan
A nuchal scan, or nuchal translucency (NT) scan, is often used as a screening test mainly for Down’s syndrome, as well as Edward’s and Patau’s syndromes and a number of major foetal abnormalities. The risk of Down’s syndrome and certain other abnormalities increases with the mother’s age.

What is nuchal translucency (NT)?
Nuchal translucency is a collection of fluid under the skin at the back of your baby’s neck. It is measured using ultrasound in order to evaluate risk of a Down’s syndrome. All babies have some fluid at the back of their neck, but those with Down’s syndrome will have an increased amount.
