NT stands for Nuchal Translucency, which translates to "Neck Translucency". The thickness of the nuchal translucency zone at the back of the neck can be seen on ultrasound, and the greater the thickness of the NT, the higher the likelihood that the fetus will have certain congenital disorders.
Detecting fetal NT thickness can help determine whether a fetus is at risk for chromosomal abnormalities, heart and other congenital disorders. For pregnant women, an NT test can provide an early indication of the health of the fetus so that appropriate measures can be taken to protect the health of the fetus.
The NT test is usually performed around the 12th week of pregnancy, and pregnant women need to make preparations, such as eating a light diet, having smooth bowel movements, and staying in a happy mood. During the test, the doctor should use high signal-to-noise ratio ultrasound equipment for the test to ensure the accuracy of the results. In addition, pregnant women should follow the instructions of medical experts to process the test results and take appropriate measures in a timely manner.
