Patient's question:
NoDoctor's answer:
During pregnancy weeks 22-26, it is recommended to undergo a 4D color ultrasound for prenatal screening to check for gross fetal abnormalities and the development of major organs. At weeks 22-26 of pregnancy, a 4D color ultrasound for prenatal screening is necessary. The 4D color ultrasound can provide a three-dimensional display of the fetus's color, face, and the development of various organs, and it can also observe the fetus's condition within the mother's body. For fetal abnormalities such as cleft lip, cleft palate, skeletal development disorders, cardiovascular malformations, etc., early diagnosis can be achieved.
