What is this test?

Hepatic vein Doppler is an ultrasound measurement of blood flowing through the veins that return blood from the liver. It records the maximum velocity during the systolic and diastolic portions of the heartbeat while you inhale.

Why might I need this test?

This test may be used to evaluate liver blood flow, investigate symptoms such as abdominal swelling, or assess possible congestion or impaired blood return from the liver. It may also help monitor certain liver or heart conditions.

How is the test performed?

You lie on your back while a technician moves an ultrasound probe over your right upper abdomen. The machine uses sound waves to measure and display the speed and direction of blood flow in the hepatic veins.

How do I prepare for the test?

No blood draw or special preparation is usually required. Wear comfortable clothing, and follow the imaging center's instructions about eating, drinking, and other tests beforehand.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Is this a blood test?
No. It is a noninvasive ultrasound test that measures blood flow without using a needle.
Does the test involve radiation?
No. Doppler ultrasound does not use ionizing radiation.
Why are measurements taken during breathing?
Breathing changes pressure and blood flow in the chest and abdomen. Measuring during inspiration helps the radiologist evaluate hepatic venous flow under standardized conditions.
