What is a cerebrovascular exam?
A cerebrovascular exam uses ultrasound to examine blood flow in the neck and arteries that supply the brain (carotid and vertebral arteries). As the blood leaves the heart via the aorta, it circulates through the carotid and vertebral arteries on each side of the neck into the head.
During a cerebrovascular exam, the technologist will pass a transducer over both sides of the neck. The test includes evaluation of the common carotid arteries, external carotid arteries, internal carotid arteries and vertebral arteries.
