Patient's question:
I've been pregnant for a while, and everyone says I need to have a 4D ultrasound examination to check if there are any special conditions with the fetus. But I don't want to do the check. Do I need to have a 4D ultrasound during pregnancy?Doctor's answer:
The main purpose of a 4D ultrasound is to screen for fetal developmental abnormalities. Generally, 1-3 sessions are sufficient. If your family has more financial resources, you can opt for three screening sessions. The first 4D ultrasound screening can be done around the 14th week of pregnancy. The second 4D ultrasound major anomaly screening is typically performed between the 22nd and 28th weeks of pregnancy, as this is when significant fetal abnormalities can be detected. Additionally, another minor anomaly screening is recommended between the 28th and 32nd weeks of pregnancy to recheck whether the fetal organs are developing properly.Generally, if your family has limited financial resources, you may only be able to afford one 4D ultrasound session. It is recommended to choose the major anomaly screening between the 22nd and 28th weeks of pregnancy, as this offers the best cost-effectiveness at this stage.
