Arterial Duplex Study

An Arterial Duplex Study is also known as LEAI (lower extremity arterial imaging) or UEAI (upper extremity arterial imaging). This test will check the arterial circulation in the arms or legs. This non-invasive test does not use needles, drugs or dyes. The test will be performed by a highly skilled ultrasound technologist.

A small amount of gel is applied to the skin over the area to be studied. A hand held transducer is used to make the pictures. The pictures will show the walls of the arteries, blood flow through the arteries and any plaque formation in the arteries. The velocity of the blood flow will be measured. This will pinpoint the level and severity of disease, if any.

Your doctor may order additional testing if this test is abnormal. This test always includes an ABI (ankle brachial index). Blood pressures are taken in both arms and ankles. The pressures are compared and calculations performed to estimate the severity of disease.

Patient Instructions:

1. Allow 45 minutes for one arm or leg and 1 1/2 hours for both extremities.

2. Wear two-piece clothing.

3. Take all of your regular medications, unless otherwise instructed by your physician.

4. Your physician will be notified of the results.

If you have additional questions about the procedure or instructions, contact your cardiologist.
