Carotid (kuh-ROT-id) ultrasound is a procedure that uses sound waves to look at blood flow through the carotid arteries. The carotid arteries are a pair of blood vessels on each side of the neck. They deliver blood from the heart to the brain. A carotid ultrasound also checks the thickness of the carotid artery wall and for blood clots.
Ultrasonography uses sound waves to create a computerized image of tissues in your neck. The technician uses a wand-like device (transducer) over your neck to do the test.
