Best 4-D Color Doppler Time

The best four-dimensional color Doppler ultrasound time should be selected at about 23 weeks. Because, at this time, the amount of amniotic fluid is relatively large, and the various organs of the fetus are basically well developed, it can be well used to see the development of various organs of the fetus. During pregnancy, regular prenatal examinations should be done. A month after the four-dimensional color Doppler ultrasound, we should also do a color B ultrasound examination, you can understand, there may be four-dimensional color Doppler ultrasound, did not find fetal development abnormalities. In addition, in the later stages of pregnancy, the left decubitus position should be selected, because after the middle and late stages of pregnancy, the uterus will normally be in a right-handed state, which will affect the blood perfusion of the uterus and placenta. The left decubitus position can improve the blood perfusion of the placenta and uterus, prevent the occurrence of fetal hypoxia, and at the same time, reduce the supine syndrome of pregnant women.
