The carotid arteries are the major blood vessels on each side of your neck that are responsible for carrying blood to your brain from your heart. The Carotid Doppler or Ultrasound is a painless and safe test that your doctor will use to look for any narrowing or blockages that may increase your risk of stroke. These arteries are most commonly blocked by a buildup of plaque, made up of fat, cholesterol and other substances.
