Carotid Duplex Test

The carotid duplex test is ordered to see if there is any blockage to the carotid arteries. The type of ultrasound machine that is used in this test is called a "duplex." This machine sends sound waves into the body, and the sound bounces back to create a picture of the blood vessels and the surrounding tissue in your neck.

What will happen during the test?

• For the test, you will be asked to lie on your back, and the exam room will be dark.
• A gel-like substance will be applied on your neck, and a technologist will guide a "probe" along your neck.
• This procedure is totally painless and takes about one hour to complete.
