ReviewClinical Distinction of Cerebral Ischemia and Triaging of Patients in the Emergency Department: Mimics, Wake-ups, Late Strokes, and Chameleons.
Non-stroke conditions may present in ways suggestive of ischemic stroke (ie, stroke mimic). Alternatively, the clinical presentation of ischemic stroke can vary considerably and may appear similar to another condition (ie, stroke chameleon). Common and uncommon mimics and chameleons are presented with discussion of key considerations to improve diagnostic accuracy.

ReviewMR Imaging Selection of Acute Stroke Patients with Emergent Large Vessel Occlusions for Thrombectomy.
Acute stroke caused by large vessel occlusions (LVOs) are common. The time window to treat is up to 24 hours, and the most important factor is the size of the ischemic core. ⋯ The necessary sequences are obtainable rapidly, comparable to computed tomography scans. Available evidence suggests that most patients with LVOs are slow progressors defined as having a small core 6 hours or more after ictus onset.
