title: Clinical neuroimaging approaches to cerebrovascular diseases.
abstract: Because of the importance of therapeutic implications, strokes must first be differentiated into ischemic or hemorrhagic; although such differentiation is often suggested clinically, it usually must be verified by computed axial tomography (CT scan). This discussion reflects this first, broad subdivision of strokes into ischemic or hemorrhagic; within these two subdivision, further discussion is related to specific etiopathologic processes.
