Abstract
Rapid identification of stroke mimics, such as seizures, is a critical part of the evaluation of patients presenting with acute focal neurological deficits. The primary role of CT perfusion is in identification of patients with acute ischemic stroke who may be candidates for reperfusion therapy, but also holds promise as a modality for identifying a seizure etiology. We review the literature on this topic and attempt to define characteristic CT perfusion findings at various points along the ictal-interictal (epileptic) continuum. We suggest an approach for using CT perfusion to differentiate stroke from seizure in patients with acute onset focal neurological deficits.
