    Doppler Flow Study

    What is a Doppler flow study?

    Doppler flow is a type of ultrasound. It uses sound waves to measure the flow of blood through a blood vessel. The results are shown on a computer screen in lines called waveforms. It’s sometimes called Doppler velocimetry. A Doppler flow study may be used during pregnancy to check the health of the unborn baby (fetus). It checks blood flow in:

    • The umbilical vein and arteries

    • The baby’s brain

    • The baby’s heart

    • Other organs in the baby

    Why might I need a Doppler flow study?

    A Doppler flow study is often used when a baby has intrauterine growth restriction. This is when the baby is smaller than normal for the number of weeks of pregnancy. The waveforms may show that there isn't enough blood flow in the umbilical vessels of a baby with fetal growth restriction. This can mean that the baby may not be getting enough blood, nutrients, and oxygen from the placenta. Doppler flow is often used when a woman is pregnant with two or more babies (multiple pregnancy). 

    What are the risks of a Doppler flow study?

    The Doppler flow study is a noninvasive test. The test doesn’t harm the baby or you.

    How do I get ready for a Doppler flow study?

    You don’t need to do any special preparation before the test.

    What happens during a Doppler flow study?

    You will lie in a comfortable position on an exam table. A healthcare provider with special training does this test using a special ultrasound machine. Gel is put on your belly. This helps to send sound waves from your belly to the computer. The provider puts a device called an ultrasound transducer on your belly. It takes several minutes to check the flow in each blood vessel being tested.

    What happens after a Doppler flow study?

    The healthcare provider will talk with you about the results. If the test shows there is not enough blood flow, you may need other testing.
