Answer to Question 1

Cerebral angiography is a radiologic procedure in which a radiopaque contrast dye is injected into the carotid arteries and an x-ray is taken to visualize the arterial circulation in the brain. This test can show aneurysms, stenosis, tumors, or plaque in the arteries. A tumor can be seen as an interwoven collection of new blood vessels, or it can be seen indirectly when it distorts normal anatomy and forces arteries into abnormal positions. The x-ray image is known as an angiogram or arteriogram.
