Pregnant women do not do four-dimensional color Doppler can

Clinically, it is recommended that pregnant women do four-dimensional color Doppler ultrasound examination between 23 and 28 weeks of pregnancy. The main purpose is to understand the development of embryos through four-dimensional color Doppler ultrasound, especially whether the organs of embryos develop normally and whether soft tissues show abnormalities. Four-dimensional color Doppler resolution is very high, and can clearly see whether there is a cleft lip and other clinical phenomena, so it is best to do a four-dimensional color Doppler examination after pregnancy, to understand the health of the fetus, to understand whether the fetus has abnormalities. If not, it is likely to show that it is difficult to judge whether there are abnormal conditions for fetal development. The cost of four-dimensional color Doppler is about 500 yuan, so it is recommended to do four-dimensional color Doppler examination.
