Doctor's answer:
Hello, the best way to exclude fetal abnormalities is to have a 4D color ultrasound. It is generally best to perform the 4D color ultrasound examination between weeks 24-30 of pregnancy. A 4D color ultrasound diagnostic instrument does not emit radiation in terms of rays, light waves, or electromagnetic waves, and has no impact on human health.
