Abstract
Magnetic resonance (MR) perfusion imaging offers the potential for measuring brain perfusion in acute stroke patients, at a time when treatment decisions based on these measurements may affect outcomes dramatically. Rapid advancements in both acute stroke therapy and perfusion imaging techniques have resulted in continuing redefinition of the role that perfusion imaging should play in patient management. This review discusses the basic pathophysiology of acute stroke, the utility of different kinds of perfusion images, and research on the continually evolving role of MR perfusion imaging in acute stroke care.
摘要
磁共振（MR）灌注成像是一种有潜力的测量急性脑卒中患者脑灌注的方法，此时基于这些测量的治疗决策可能会显著影响预后。急性脑卒中治疗和灌注成像技术的快速发展，导致不断重新定义灌注成像在患者管理中应发挥的作用。本文讨论了急性脑卒中的基本病理生理学、不同类型灌注图像的效用，以及不断发展的 MR 灌注成像在急性脑卒中治疗中的作用的研究。
