Cerebral angiography

Vertebral angiogram; Angiography - head; Carotid angiogram; Cervicocerebral catheter-based angiography; Intra-arterial digital subtraction angiography; IADSA

Cerebral angiography is a procedure that uses a special dye (contrast material) and x-rays to see how blood flows through the brain.

Brain

The major areas of the brain have one or more specific functions.

Carotid stenosis, X-ray of the left artery

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.

Carotid stenosis, X-ray of the right artery

This is an angiogram of the right carotid artery showing a severe narrowing (stenosis) of the internal carotid artery just past the carotid fork. There is enlargement of the vein or ulceration in the area after the stenosis in this close-up film. Note the narrowed segment toward the bottom of the picture.
