Doppler velocimetry

Doppler velocimetry

Obstetrics A technique used to analyze blood flow waveforms, allowing accurate noninvasive measurement of volume and velocity of blood flow

Doppler velocimetry

The use of Doppler ultrasound to determine the speed of blood flow through arteries and veins. During pregnancy Doppler ultrasonography can determine whether blood flow rates are adequate in the uterine artery, placenta, and umbilical cord vessels.

Placental insufficiency is the primary cause (60%) of intrauterine growth restriction in normally formed fetuses and can be identified using umbilical artery Doppler velocimetry.
