Wondering if the fetus has internal organ abnormalities, what tests are needed

Patient's question:

No

Doctor's answer:

During the 22-26 weeks of pregnancy, a 4D color ultrasound screening for fetal anomaly is recommended to assess whether the fetus has any major malformations and the development of major organs. 4D color ultrasound can perform ultrasound examinations on the fetus, providing a three-dimensional display of the fetus's color, face, and the development of various organs. It can even observe the fetus's condition within the mother's body. For fetal anomalies such as cleft lip, cleft palate, skeletal developmental abnormalities, cardiovascular malformations, etc., early diagnosis can be achieved.
