During your pregnancy two of the most common scans you will be referred for, are the Nuchal Translucency (NT) Scan and a Morphology Scan. An NT scan is a screening test to establish if your pregnancy has a high risk of Down Syndrome or other chromosomal conditions. It involves a blood test and an ultrasound.
Ideally, you arrange for your blood test to be carried out first, from about 9 weeks. You can then book your NT ultrasound scan between 12 weeks and 13 weeks and 6 days. The Morphology Scan is used to assess the well-being of your baby and to check your dates. This scan is performed during your pregnancy between 18 to 22 weeks. There are established and strict criteria for the accurate measurement of the nuchal translucency. Our fully trained and ASAR accredited sonographers perform these ultrasounds. It is important to bring in any prior scans you may have for your pregnancy.
Nuchal Translucency is the fluid found at the back of your baby’s head and neck, just beneath the skin. The thickness of this fluid can be precisely measured. Data gathered from the scan measurement, blood test results and personal information are used to calculate either a low risk or high risk outcome.
It is a screening ultrasound. It is a non-invasive way of providing information about your baby’s risk of certain chromosonal abnormalities (trisomy 13, 18 and 21).
You should arrange your scan between 12 weeks and 13 weeks and 6 days gestation.
