Four-dimensional color Doppler ultrasound is mainly used in obstetrics. It can observe the development and movement of fetal limbs and limbs, screen fetal facial abnormalities, construct three-dimensional fetal heart, and carefully examine hemodynamics. Because the process of four-dimensional color Doppler ultrasound examination is complicated, and the examination time is relatively long, pregnant women should eat a little when doing the examination, and need to bring a little sweet food around. Therefore, four-dimensional color Doppler ultrasound does not require fasting, but rather to eat. If the fetal position does not cooperate, pregnant women need to go out for a walk, eat a little chocolate and other high-energy foods to promote fetal activities, which is more conducive to color Doppler ultrasound to observe the fetal face, limbs and organ development from all angles.
