NT examination refers to the use of ultrasound to measure the thickness of the nuchal translucency of embryos. It is one of the screening items for prenatal examination of fetuses and an effective imaging method for early detection of fetal abnormalities. The thickness of NT has significant clinical implications. The development of the fetus can be examined by observing the increase in NT thickness. So, should I go to obstetrics or gynecology for NT?
NT examination is an obstetric examination that measures the thickness of fetal neck transparency through B-ultrasound examination to determine whether there is a risk of fetal malformation. This is an early Down syndrome screening examination.
If the NT test results exceed the standard range, it is recommended that pregnant women undergo subsequent screening to further confirm the risk of fetal abnormalities and take early response measures. This type of screening is mainly done through ultrasound scanning, usually done on the pregnant mother's belly with B-ultrasound, but it also depends on the position of the baby and uterus. If necessary, vaginal B-ultrasound can be used to see more clearly.
NT examination can also screen for early fetal structural abnormalities, which can be considered as a small screening for abnormalities, so it is very necessary. When measuring NT, the ultrasound probe can be used to measure through the abdomen without holding urine. The best time to measure fetal NT thickness is between 11 weeks and 13 weeks plus 6 days of pregnancy.
