Multiparametric MR Guidance of Acute Stroke Treatment

A. Gregory Sorensen ¹

MRI has become a standard method for diagnosing acute ischemic stroke. The development of diffusion MRI, perfusion MRI, MRA, and other techniques have provided tremendous insight into the pathophysiology of stroke and offered substantial improvements in patient management. Advances in hardware, pulse sequences, and post-processing methods are still needed to fully exploit the opportunities that MR provides to improve patient outcomes. This lecture will review the successes as well as the unmet needs in stroke, with an eye to both validation of existing methods and development of newer approaches.
