Carotid Ultrasound

Carotid ultrasound is a safe, noninvasive, painless procedure that uses sound waves to examine the blood flow through the carotid arteries. It also evaluates the thickness of the carotid artery wall and checks for clots.

One carotid artery is located on each side of the neck. These arteries deliver blood from the heart to the brain.

A carotid ultrasound tests for blocked or narrowed carotid arteries, which can increase the risk of stroke. The results of the test can help your health care provider determine a treatment to lower your stroke risk.
