During a CT scan, the patient lies on a table inside a tube. The tube takes detailed X rays of portions of the human body at different angles to form three-dimensional images. A CT scan can give your physician extensive information about where you may have narrowing in the carotid arteries. For the test, you may also be administered contrast dye, a substance that makes it easier to see the blood vessels. A CT scan uses radiation to form images, so the benefits and risks are weighed before this type of scan is performed.
