The optimal time for twins to undergo 4D color ultrasound
Disease description:
I am pregnant with twins and I know that the 4D color ultrasound is very important for fetal anomaly screening. However, I am not sure about the best timing for this examination. Could you please advise when is the most appropriate time for twins to undergo a 4D color ultrasound?

Dr. Zhang Lu
The optimal time for twins to undergo a 4D color ultrasound is generally recommended between the 20th and 24th weeks of pregnancy. However, the specific timing should be determined according to the individual condition of the pregnant woman and the professional advice of her doctor.
During this period, the fetus's organs have largely completed development but have not yet entered the phase of rapid growth. Therefore, a 4D color ultrasound can clearly visualize the structures, movements, and interactions of the two fetuses, while also assessing important indicators such as amniotic fluid volume and placental position.
At this stage, fetal organ development is largely mature, and the amniotic fluid volume is moderate, with increased fetal movement inside the uterus, which facilitates obtaining clear images. A 4D color ultrasound allows comprehensive observation of fetal growth and development from multiple angles and planes, providing a scientific basis for early diagnosis of congenital body surface malformations and other congenital diseases.
Pregnant women are advised to choose hospitals with specialized expertise for the examination to ensure accuracy and reliability. Additionally, pregnant women should avoid consuming high-fiber foods and gas-producing beverages before the examination, as these may interfere with the results.
