Cerebral Infarct/Intracranial Cerebrovascular Disease

Abstract

Imaging goals for intracranial cerebral vascular disease are (1) to assess the degree of parenchymal injury and identify intraparenchymal hemorrhage; (2) to determine if there are areas of altered perfusion that may be at risk for future injury; and (3) to assess the intracranial arteries (patency as well as direction of flow). This unit describes a Basic Protocol that can be used to evaluate stable patients with acute, subacute, or chronic cerebrovascular symptoms. An Alternate Protocol is also given for cases of hyperacute strokes or cerebrovascular symptoms in an unstable patient.
