Pregnant a few months to do four-dimensional b ultrasound is the most appropriate

During the pregnancy period of 22-26 weeks, it is most appropriate for expectant mothers to do four-dimensional color Doppler ultrasound. Because in this time period, four-dimensional color Doppler ultrasound examination can more clearly see the dynamic situation of the fetus in the mother's uterus. Therefore, it is recommended that pregnant women must come to the hospital for examination within this gestational week, and must make an appointment in advance. The above health science knowledge is for reference only, and the specific situation needs to be checked in a regular hospital, and judged by a professional doctor.
