ce·re·bral an·gi·og·ra·phy

radiographic visualization of the blood vessels supplying the brain, including their extracranial portions; the injection of contrast medium may be made percutaneously, by open exposure and puncture of the carotid artery or by catheterization after introduction of the catheter at a distant site.

Etymology: L, cerebrum, brain; Gk, angeion, vessel, graphein, to record
a radiographic procedure used to visualize the vascular system of the brain after injection of a radiopaque contrast medium.

Although conventional cerebral angiography provides comprehensive evaluation of the carotid distribution, including accurate characterization of plaque and collateral circulation (4), the risk of neurological complications (4%) and even death (1%) has led to its relatively uncommon use (5).

Cerebral angiography revealed that the tumor was primarily supplied by three branches of the left external carotid artery--the left posterior occipital artery, the ascending pharyngeal artery, and the posterior auricular artery--with a minor contribution from the petrous branch of the left internal carotid artery.
The diagnosis can be considered based on MR and computed tomographic angiography findings, although cerebral angiography is considered the gold standard for suggesting the diagnosis.
