When is the best time to have a 4D color ultrasound?
I am currently five months pregnant. I remember that a four-dimensional color ultrasound (4D ultrasound) will be performed later. Doctor, I would like to ask, when is the best time to have a 4D ultrasound?
Doctor's answer (1)
Four-dimensional color ultrasound is one of the important examinations during pregnancy. The optimal time for examination is generally recommended between 22 to 28 weeks of gestation, approximately six months after the last menstrual period.
During this period, the overall structure of the fetus has formed, the size is moderate, and there is an appropriate amount of amniotic fluid. The fetus has sufficient space for movement within the uterine cavity, allowing clear visualization of various fetal tissues and improving the accuracy of anomaly screening. Additionally, the fetal brain is undergoing rapid development, and the interference from bone echoes is minimal, resulting in clearer images. Therefore, performing four-dimensional color ultrasound during this period enables pregnant women to better understand fetal development and promptly identify and address any issues.
The exact timing of the examination should be determined based on the individual circumstances of the pregnant woman and the recommendation of her physician.
