Patient's question:
NoDoctor's answer:
The best time to do a 4D ultrasound is between weeks 24 and 28 of pregnancy, because during this period the fetus's limbs and major organs have fully developed, and the amniotic fluid is more suitable for fetal anomaly screening. However, due to individual differences among pregnant women, please contact your doctor to determine the specific time for the 4D ultrasound according to medical advice. The 4D ultrasound can observe the growth and development of the fetus in the uterus from multiple directions and angles, providing accurate scientific evidence for early diagnosis of congenital external malformations and congenital heart diseases in the fetus.
