【摘 要】目的：观察磁共振弥散加权成像(DWI)在急性脑梗死中的应用效果，探讨其临床价值。方法：选取我院2017年7月～2018年7月期间收治的经磁共振检查与临床治疗证明有效的60例急性脑梗死患者作为研究对象，对其临床资料进行回顾性分析，总结患者各期病灶在DWI序列以及MR常规序列中的检出数量、信号强度、病灶大小。结果：超急性期与急性期患者的DWI序列均显示梗死灶，而常规序列中，仅部分患者显示出病灶，且其显示的梗死面积明显小于DWI序列。结论：在急性脑梗死患者的早期诊断与治疗中，DWI对超急性期、急性期、亚急性早期脑梗死的诊断价值明显高于常规MRI检查，可作为临床诊断与治疗的重要依据。

【Abstract】Objective：Observe the effect of diffusion weighted magnetic resonance imaging (DWI) in acute cerebral infarction and to explore its clinical value.Methods：Sixty patients with acute cerebral infarction who were admitted to our hospital from July 2017 to July 2018 and proved effective by magnetic resonance examination and clinical treatment were selected as the research objects. Their clinical data were retrospectively analyzed. The number ......
