Is it okay to have a 4D ultrasound after seven and a half months?

Patient's question:

No

Doctor's answer:

Generally, it is possible. During the 22-26 weeks of pregnancy, a 4D color Doppler ultrasound is required for prenatal screening to detect abnormalities. The 4D color Doppler ultrasound can display the fetus's color, face, and development of various organs in three dimensions, and even observe the fetus's condition inside the mother's body. It can also help diagnose early abnormalities in the fetus, such as cleft lip, cleft palate, skeletal development abnormalities, cardiovascular malformations, and more.
