Health Management for Older Adults III - Emergency Response to Stroke -- The Questions

< i > Emergency Response to Stroke -- The Questions

The third question is whether the stroke is an infarction or a hemorrhage.

Only an imaging study can address this question. Hemorrhages can masquerade as any type of ischemic event.

A CT scan is far preferable to an MRI scan because hemorrhages uniformly appear white on CT scans, whereas they exhibit a complex sequence of signal alterations on MRI scans. Hemorrhagic infarcts, that is infarcts with blood scattered through them, have the same significance and pathogenesis as ischemic infarcts.
