NT is the thickness of the nuchal translucency of the fetus, which is a clinical ultrasound soft indicator used to check for abnormalities in the fetus and an effective imaging method. This protocol can also be used to examine twins in vivo. So, how long does it take for twins to do NT?
The probability of a typical woman carrying twins is 1:89, which means that on average, out of 89 pregnant women, one twin will appear. Twins can be divided into monozygotic twins and dizygotic twins. The former are developed from the same fertilized egg, while the latter are developed from different fertilized eggs. In order to have a clearer understanding of the development and growth status of twins in the body, NT examination can be performed at the hospital, which can screen for 60-70% of fetuses with chromosomal abnormalities and provide timely treatment.
NT examination is a method of ultrasound examination, and the results can be obtained on the same day of examination. The general process only takes a few minutes, mainly to check the transparent band of the twin's neck to see the gap of subcutaneous water accumulation. The thicker the transparent band of NT screening, the higher the risk of congenital diseases in twins. It is recommended to conduct screening around 11-13 weeks of pregnancy.
In addition, women who are pregnant with twins will face more difficulties, especially in the middle and late stages of pregnancy when their abdomen will protrude significantly, and lower back pain and lower limb edema may be more severe. Therefore, it is important to pay attention to rest. And it is necessary to strengthen the density of prenatal examinations, as having two babies will put a heavier burden on the mother, so paying attention to prenatal examinations will be more important.
