Doppler

Close-up image of a pregnant woman having an ultrasound.

The Doppler test measures blood flow in different parts of your baby’s body, including:

  • Umbilical cord
  • Brain
  • Liver
  • Heart

This allows your physician to get information about your baby’s health. Usually, this test is performed at the same time as an ultrasound and uses the same equipment.


Frequently Asked Questions

Why is a Doppler performed?

A Doppler may be performed when there is a known or suspected abnormality or condition that may alter the blood flow in the fetal or placental circulation, such as intrauterine growth restriction, fetal cardiac abnormalities and maternal conditions, like chronic hypertension.

Who will perform the test?

A registered diagnostic medical sonographer will perform the test.

When is a Doppler traditionally performed?

A Doppler may be performed at any point in your pregnancy when a necessity to perform it is indicated.

What can I expect during the Doppler test?

Doppler ultrasound is painless and noninvasive, and you should experience no difference from a regular ultrasound, other than sounds from the ultrasound machine created by the flow of blood in the vessel or valve being sampled. You may be asked to hold your breath or remain still while the sonographer obtains the Doppler sample.

Where is the Doppler performed?

It is performed in one of our private ultrasound suites.
