Patient's question:
NoDoctor's answer:
A prenatal ultrasound is required between 22 and 28 weeks to screen for fetal major abnormalities. The ultrasound is definitely necessary, and you can choose a color Doppler ultrasound with two or more dimensions. However, a fetal heart ultrasound is not a mandatory part of the screening. It is only necessary to perform further fetal heart ultrasound if any issues are detected.
