Carotid Duplex Scan

A Carotid Duplex Scan uses sound waves to evaluate the mail arteries in the neck which supply blood to the brain. The test is noninvasive, which means no needles, catheters, or dyes are used. Ultrasound is used to create a picture of the shape of tissues and organs inside your body. The walls of blood vessels, including any deposits or narrowing, can also be seen.

Gel is placed on the skin over the area to be studied. An instrument, called a transducer, is placed on your skin. Sound waves are transmitted from the transducer. The sound waves reflect off the tissues and organs to created a picture that can be seen on a screen. Blood flow through the blood vessels can be heard as the test is being completed.

Patient Instructions:

  1. No special preparation is required.
  2. Allow 45 minutes.
  3. Your physician will be notified of the results.
