When is the best time to have a 3D color ultrasound?

Generally, the optimal time for a 3D color ultrasound examination is between 22 and 28 weeks of pregnancy, with the best period being between 24 and 26 weeks. During this stage, the fetus is well-developed, the amniotic fluid volume is moderate, and fetal movement is active, allowing clear visualization of most tissues, organs, structures, and the overall fetal development, with a relatively high imaging success rate.

Using 3D color ultrasound, doctors can observe fetal development inside the uterus from multiple perspectives, providing accurate scientific evidence for the early diagnosis of congenital fetal abnormalities and other conditions. The specific timing of the examination may vary depending on individual differences among pregnant women and the doctor's recommendations.

Pregnant women should follow medical advice to attend regular prenatal check-ups during pregnancy and undergo 3D color ultrasound examinations as recommended by their doctors.
