Doctor's answer:
3D color ultrasound is for comprehensive anomaly screening. The images are three-dimensional, and doctors can see them very clearly. Usually, if the Down syndrome screening and 3D ultrasound pass, there's nothing to worry about—the baby is normal and healthy. It's recommended to do one 3D ultrasound followed by one 4D ultrasound.
