Imaging Approaches to Stroke and Neurovascular Disease.

Abstract

Imaging is paramount to the diagnosis and management of ischemic stroke, offering a battery of structural and functional probes of cerebrovascular physiology. The technical underpinnings of stroke imaging continue to evolve, bringing the neuroscience community increasingly closer to high-resolution, tissue-level biomarkers of brain perfusion, metabolism, and viability. The rapid expansion of neuroimaging in this domain has met with controversies, and in many respects, a lack of generalizable conclusions regarding optimized use in cerebrovascular disease. This review aims to provide the reader with the depth and scope of both established and emerging techniques, and an overview of prevailing viewpoints regarding neuroimaging in acute ischemic stroke.
