Stroke is a devastating disease with a complex pathophysiology. It is a major cause of death and disability in North America. To fully characterize its extent and effects, one requires numerous specialized anatomical and functional MR techniques, specifically diffusion-weighted imaging, MR angiography, and perfusion-weighted imaging. The advent of 3.0 T clinical scanners has the potential to provide higher quality information in potentially less time compared with 1.5 T stroke-specific MR imaging protocols. This article gives a brief overview of stroke, presents the principles and clinical applications of the relevant MR techniques required for diagnostic stroke imaging at high field, and discusses the advantages, challenges, and limitations of 3.0 T imaging as they relate to stroke.
中风是一种具有复杂病理生理学的毁灭性疾病。它是北美地区死亡和残疾的主要原因。为了全面描述其范围和影响，需要众多专门的解剖学和功能性磁共振成像（MR）技术，特别是扩散加权成像、磁共振血管造影和灌注加权成像。与1.5T中风特异性MR成像协议相比，3.0T临床扫描仪的出现有可能在更短的时间内提供更高质量的信息。本文简要概述了中风，介绍了高场诊断中风成像所需的相关MR技术的原理和临床应用，并讨论了3.0T成像与中风相关的优势、挑战和局限性。
