Overview
A carotid arteriogram is an x-ray study designed to determine if there is narrowing or other abnormality in the carotid artery, a main artery to the brain. This is an angiogram of the left common carotid artery (both front-to-back and side views) showing a severe narrowing (stenosis) of the internal carotid artery just beyond the division of the common carotid artery into the internal and external branches.
