Vertebral angiogram; Angiography - head; Carotid angiogram

Contrast dye flowing out of the blood vessel may be a sign of internal bleeding.

Narrowed arteries may suggest cholesterol deposits, a spasm, or inherited disorders.

Out of place blood vessels may be due to brain tumors, bleeding within the skull, aneurysm (bulging of the artery walls), or arteriovenous malformation.

Abnormal results may also be due to:

• Intracerebral hemorrhage
• Metastatic brain tumor
• Neurosyphilis
• Optic glioma
• Pituitary tumor
• Primary brain tumors
