Doppler ultrasound uses sound waves to detect the movement of blood in vessels. It is used in pregnancy to study blood circulation in the baby, uterus and placenta. Using it in high-risk pregnancies, where there is concern about baby’s condition, shows benefits.
When is a Doppler ultrasound used in pregnancy?

It can show blocked or reduced flow of blood through narrow areas in the major arteries of the neck.
