Pregnant women need to have a color Doppler ultrasound examination according to the time prescribed by the doctor. At present, there are two options: three-dimensional color Doppler ultrasound or four-dimensional color Doppler ultrasound.
Tips from Wuxi Baijia Maternity Hospital: You don't need to prepare for fasting and defecation for abnormal examination. Pregnant women can detect fetal malformation as long as they go to a regular hospital for examination within the examination time of four-dimensional color Doppler ultrasound. Half an hour before the abnormal color Doppler ultrasound, expectant mothers can eat something and drink some water, which can increase fetal movement.
