Use of Imaging to Guide Eligibility for Reperfusion Therapies in Acute Ischemic Stroke

Imaging is pivotal across all stages of stroke care, particularly acutely where it is central to diagnosis, prognostication, and selecting patients with a favorable benefit-to-risk profile for thrombolysis and endovascular therapy. With new therapies emerging and treatment eligibility expanding to broader patient populations, imaging strategies have evolved. This review will highlight the evolution in acute stroke imaging, examine emerging and ongoing clinical trials in which imaging is integral to patient selection, and identify priority areas for future research and development.
