Patient's question:
I am now about 20 weeks pregnant and would like to consult if a 4D ultrasound can be done at 20 weeks. Are there any precautions to be aware of?Doctor's answer:
You are currently about 20 weeks pregnant. Generally, at this stage, a detailed 4D ultrasound examination is not necessary. A 4D ultrasound is a comprehensive screening for major fetal anomalies. It is generally recommended to perform this examination during the period when fetal growth and development are more mature, which can help rule out developmental abnormalities in the fetus. At your current stage of pregnancy, the gestational age is still relatively short, and such a detailed examination can be performed between 22 and 28 weeks of pregnancy. It is recommended to regularly visit the hospital for prenatal check-ups. During this stage, you can start taking calcium supplements while also monitoring fetal movements regularly.
