Nuchal translucency scan

| | 0 Comments

There are a number of tests and scans available to you during your pregnancy. The nuchal translucency scan is an ultrasound that may detect the risk of a number of chromosomal abnormalities. A nuchal translucency scan is part of the ultrasound scan that most pregnant women have at around 12 weeks of pregnancy. The results of a nuchal translucency scan may tell you if your baby has a high or low risk of a chromosomal abnormality. Examples of chromosomal abnormalities include trisomy 21 Down syndrome , trisomy 18 Edwards syndrome or trisomy 13 Patau syndrome. The results will tell you if your baby is at high risk or low risk of chromosomal abnormality in comparison to the general population. The nuchal translucency scan is done between 11 and 14 weeks of pregnancy. Usually the scan is done through your abdomen but occasionally the nuchal translucency can only be seen by inserting a probe into the vagina.

The measurement of the nuchal translucency is part of the combined screening test for trisomy 21 and trisomy 18, called enhanced First Trimester Screen eFTS. An increased NT measurement increases the chance for other chromosome differences, additional genetic conditions, and can also be helpful to predict structural differences that might be more obvious later in pregnancy such as a heart defect.

Fetuses with increased fluid at the base of their necks — a spot known as the nuchal fold — may have a chromosomal problem such as Down syndrome. Nuchal translucency is a prenatal screening , which means the results can’t tell you for sure whether your child has a chromosomal disorder, only the statistical likelihood.

It’s often combined with a blood test to offer more insight into the relative odds of your baby being born with a genetic disorder. An NT screen is often part of routine prenatal testing during the first trimester and is recommended for all women. While it’s widely available, some areas especially rural ones may not have the machine and technicians with the experience to perform the procedure.

For the new mum to be, Ultrasound scans are the highlight of her pregnancy. Ultrasound scans use sound waves to build a picture of your baby in the womb.

The scan applies ultrasound technology so the procedure is also non-invasive and painless. You will be scheduled for an ultrasound between 11 and 14 weeks into pregnancy. This timing ensures that the baby is not too small for the test to be effective, and not too developed that any surplus fluid is naturally absorbed. A scan of the vagina may afford a more precise view of the baby, especially if the test is taken early, but most NT scans are taken through the abdomen.

They then calculate the size of nuchal translucency, which appears on the scan as black between white lines of skin. They enter these figures into a record containing the general risk for mothers of this age, and both the age and measurements are then mixed to calculate an individual risk factor. Depending on the NT measurement, your risk can be greater or less than the general risk for women your age.

There is usually no reason why you cannot bring your partner, a friend or family member with you for support and to share the moment of seeing your baby.
