What is NT Scan in Pregnancy

What is NT Scan in Pregnancy

An NT scan, or nuchal translucency scan, is a type of ultrasound performed during the first trimester of pregnancy, typically between 11 and 14 weeks. It measures the thickness of the fluid-filled space at the back of your baby's neck, called the nuchal translucency (NT).

What is the purpose of an NT scan?

The main purpose of an NT scan is to assess your baby's risk of having certain chromosomal abnormalities, such as Down syndrome, Edwards syndrome, and Patau syndrome. These conditions are caused by an extra chromosome being present in each cell of the body.

How is an NT scan performed?

An NT scan is a painless and non-invasive procedure. You will lie on your back on an examination table, and a sonographer will apply a gel to your abdomen. They will then use a handheld ultrasound probe to create images of your baby. The sonographer will measure the thickness of the NT and take other measurements of your baby, such as their crown-rump length.

What do the results of an NT scan mean?

A thicker-than-normal NT measurement may indicate an increased risk of chromosomal abnormalities. However, it is important to remember that an NT scan is a screening test, not a diagnostic test. This means that it cannot definitively tell you whether or not your baby has a chromosomal abnormality. If your NT scan results show an increased risk, your doctor may recommend further testing, such as amniocentesis or chorionic villus sampling (CVS). These tests can diagnose chromosomal abnormalities with more certainty.

What are the benefits of having an NT scan?

An NT scan can provide valuable information about your baby's health. It can help you to make informed decisions about your pregnancy, such as whether or not to have further testing.

What are the risks of having an NT scan?

An NT scan is a safe procedure with no known risks to you or your baby.

Who should consider having an NT scan?

All pregnant women are offered an NT scan, but it is up to you to decide whether or not to have one. There are a number of factors to consider, such as your age, family history, and personal preferences. You should discuss the pros and cons of an NT scan with your doctor.
