Introduction
NT scan is a prenatal screening method used to detect whether the fetus has chromosomal abnormalities. The NT scan should be performed between 11 and 14 weeks of pregnancy; undergoing the examination beyond this timeframe may affect the accuracy of the results. If you wish to have an NT scan, it is recommended to go to a正规 hospital and choose a qualified physician to ensure reliable results.
Generally, NT scan is a prenatal screening method used to detect whether the fetus has chromosomal abnormalities. The specific procedure is as follows:
1. Have the pregnant woman lie down and expose her abdomen.
2. The doctor applies coupling gel to the pregnant woman's abdomen, then places an abdominal ultrasound probe on the abdomen so that ultrasound waves enter and reflect back, forming images.
3. Obtain the mid-sagittal section of the fetus in its natural flexed position using ultrasound imaging. Magnify the ultrasound image until the fetal head and upper chest occupy approximately 75% of the screen.
4. Measure the maximum thickness of the translucent tissue between the fetal neck soft tissue and skin. Perform at least three measurements and record the largest value for analysis.
The NT scan should be performed between 11 and 14 weeks of gestation. Performing the scan beyond this time frame may affect the accuracy of the results. If you plan to undergo an NT scan, it is recommended to visit a reputable hospital and choose an experienced physician to ensure accurate results.
