What is a carotid angiography?
Carotid angiography is a diagnostic imaging tool that uses dye, or contrast, and a special X-ray machine to study the health of veins, arteries and blood flow.
Carotid angiography is the best test available to identify and measure blockages in the carotid arteries of the neck. The test may also show whether surgery to reopen a blocked blood vessel is the best medical option, as well as determine the patient’s risk for a future stroke.
