Abstract

This article reviews the current state of imaging for acute ischemic stroke. Protocolized imaging acquisition using computed tomography in conjunction with coordinated stroke care allows for rapid diagnosis and prompt revascularization. Following the initial evidence to support endovascular therapy for large-vessel occlusion, published between 2014 and 2015, there are now guidelines supporting treatment up to 24 hours after time of onset of symptoms. Neuroimaging remains a central component in diagnosing acute stroke and potentially excluding patients from stroke treatment, as outlined in this article.

Keywords: Acute ischemic stroke; Computer tomography perfusion; Endovascular therapy; Large-vessel occlusion; Neurointervention; Thrombectomy.
