Rule Out (R/O) Intracranial Aneurysm

When imaging patients for intracranial aneurysm, the goals are: (1) to assess the contour of the intracranial arteries, particularly in he regions of the ACOM (anterior communicating artery), PCOM (posterior communicating artery), ICA (internal carotid artery) bifurcation, MCA (middle cerebral artery) trifurcation, basilar tip, and PICA (posterior inferior cerebellar artery); (2) to assess the anatomy of the Circle of Willis and direction of flow, and; (3) to determine if there is evidence of a recent subarachnoid bleed. This unit describes a that can be used for standard imaging of aneurysm in stable patients. An is described for situations when there is concern for vasospasm and infarction.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/145398/1/cpmia0102.pd
