Patient's question:
Yesterday, I went to the hospital with my wife for a prenatal check-up. The doctor said we needed to have a 4D ultrasound done. What is a 4D ultrasound for a pregnant woman?Doctor's answer:
After pregnancy, to achieve the goal of healthy and optimal fetal development, regular prenatal check-ups are necessary throughout the entire pregnancy. The 4D ultrasound is a comprehensive ultrasound examination during the entire pregnancy, specifically performed between weeks 22 and 26, primarily to rule out fetal abnormalities. If any abnormalities are detected during the examination, further tests may be required, such as amniocentesis or cardiac ultrasound. If the examination shows no special findings, a second ultrasound for fetal anomaly screening is recommended around week 30 of pregnancy.
