Definition

This test uses ultrasound to examine the blood flow in the major arteries and veins in the arms and legs.


How the test is performed

The test is done in the ultrasound or radiology department or in a peripheral vascular lab.

To examine the veins:

A water-soluble gel is placed on a handheld device called a transducer, which directs the high-frequency sound waves to the artery or veins being tested.

To examine the arteries:

Blood pressure cuffs may be put around different parts of the body, including the thigh, calf, ankle, and different points along the arm. A paste is applied to the skin over the arteries being examined. Images are created as the transducer is moved over each area.





How to prepare for the test

You will need to remove clothing from the arm or leg being examined.


How the test will feel

There is little or no discomfort associated with this test.


Why the test is performed
