Patient's question:
NoDoctor's answer:
Hello, it is recommended to undergo a 4D color Doppler ultrasound during the 22-26 weeks of pregnancy to understand if the fetus has any major malformations and the development of its main organs. At 22-26 weeks of pregnancy, a 4D color Doppler ultrasound is needed for prenatal screening of malformations. The 4D color Doppler ultrasound can display the color, face, and development of each organ of the fetus in three dimensions, and even the state of the fetus in the mother's body can be observed.
