cerebral angiography

a noninvasive technique for examining brain structure by taking X-rays after special dyes have been injected into cerebral blood vessels. Inferences about adjacent tissue can be made from examination of the principal blood vessels. It has been largely superseded by techniques based on magnetic resonance imaging, such as magnetic resonance angiography. Also called cerebral arteriography.
