Patient's question:
I am 22 weeks pregnant. During the 20-week prenatal checkup, the doctor asked me to schedule a 4D ultrasound and emphasized several times that it was essential to do it, saying it was very important for checking if the baby had any abnormalities. The doctor also asked me to come back and learn about the relevant knowledge of 4D ultrasound.What kind of help do I need: What does the 4D ultrasound check for?
Doctor's answer:
4D ultrasound is affected by many factors such as fetal position, different gestational weeks, placenta, amniotic fluid, etc. To obtain better 4D imaging results, it is recommended that pregnant women undergo the examination during the following gestational weeks. The best period is from 12 weeks to 32 weeks, and it is generally more suitable to do it between 24 weeks and 28 weeks of pregnancy. At this stage, the structure of the fetus has already formed, the size of the baby and the amount of amniotic fluid are moderate, and there is more space for the fetus to move inside the uterus. The echo of fetal bones has a smaller impact, and the image is also clearer.
