What is the major fetal anomaly screening during pregnancy?

"Major fetal malformation screening" is a detailed B-ultrasound examination to see if there are serious malformations in the development of the fetus, and then to rule out malformations. This examination is usually performed at 20-24 weeks. Because the fetus is in a period of rapid brain development at around 24 weeks, the structure of the fetus has been formed, the size of the fetus and the amniotic fluid are moderate, there is a lot of room for movement in the uterus, the fetal bone echo is less affected, and the image is clearer.

Color Doppler ultrasound examination can rule out most fetal malformations, but due to different times and fetal positions, the images generated are also different. Therefore, it is not possible to completely rule out all fetal malformations.
