What is An Arterial Duplex?
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.
An arterial duplex scan uses high frequency sound waves, known as an ultrasound, to take images of many major arteries in the body. It is commonly used for the arteries in the neck, arms, and legs. Duplex arterial scans allow doctors to see any plaque build up that may be in the arteries.
A Doppler ultrasound can also be used to allow doctors to see images of the blood traveling through the arteries. This allows doctors to see if the blood is flowing properly and if there may be a build up.
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.
Who requires an Arterial Duplex
Doctors often use a diagnostic tool, known as a duplex arterial scan, to take images of the arteries inside the arm, neck, and legs. This procedure is more commonly known as an arterial duplex scan.
This procedure is a very simple and pain free tool used by doctors to properly diagnose many medical conditions.
