Carotid doppler, also known as carotid ultrasound, is an easy, painless test that evaluates the inside of the carotid arteries, which are vessels that pass through the side of the neck and carry oxygen to the brain.
When there are health problems, such as high cholesterol or high blood pressure, there may be a buildup of fat in the wall of this artery, which eventually decreases blood flow to the brain. In addition, these small fat plaques can also rupture, forming a clot that can be transported to the brain and cause a stroke.
