Is it necessary for pregnant women to have a 4D ultrasound? Are there any effects?

Patient's question:

No

Doctor's answer:

Hello, yes, 4D color Doppler ultrasound can better rule out the child's problems and is more comprehensive than general color Doppler ultrasound. 4D color Doppler ultrasound is optional; you can choose not to have it done. Wishing you good health!
