Nuchal translucency ultrasound alone can also provide this risk assessment, but it is not as accurate as combined first trimester screening.
During the scan we will measure the amount of fluid at the back of your baby’s neck (Nuchal Translucency).
Using this measurement, along with the mother’s age, the age of the baby and the presence or absence of the baby’s nasal bone, a risk is calculated to determine the likelihood of your baby having a chromosomal abnormality. If the calculation gives you an increased risk, you may be happy to continue without further investigation or you may feel you want a more definite answer.
Nuchal Translucency is a combined screening test, which involves an ultrasound scan and a blood test.
This gives the most accurate result for assessing the risk of Down’s syndrome in a foetus during pregnancy.
This test gives us an indication of whether we should worry about your baby based on these results.
This means that combined first trimester screening will not give us a definitive answer.
A Nuchal Translucency (NT) scan is a screening test that is carried out to assess whether a baby is likely to have Down’s syndrome or other chromosomal abnormalities.
The NT scan cannot diagnose whether a baby has Down’s, it only estimates the risk.
Some baby's are in a great position for us to be able to take their photo, other babies are shy and like to hide behind their hands and feet, the umbilical cord or the placenta which can make it a little difficult to get a clear 3D image.
Don't be discouraged if your images are not front on or as clear as you hoped due to the above factors, the most important part of the scan is the assessment of your baby's growth and wellbeing and we will do our best to ensure you still have some images of your baby to go home with to show your family and friends.
A nuchal translucency ultrasound (commonly called a “nuchal scan” or “NT scan”) is an ultrasound performed between 11.5 and 13 weeks 6 days gestation.
