摘　　要：脑梗死是常见的脑血管疾病,该病常疾病发作,发作后常会出现缺血半暗带,针对这一疾病若不及时诊治会威胁患者的生命健康。针对疾病的诊断,目前多采取M R扩散及灌注成像的方法,本研究中,具体对M R扩散(D W I)及灌注成像(PWI)联合诊断超急性脑梗死缺血半暗带的相关研究做一综述。Cerebral infarction is a common cerebrovascular disease,which often occurs and often appears ischemic penumbra after onset.If not diagnosed and treated in time,it will threaten the life and health of patients.At present,MR diffusion and perfusion imaging are mostly used in the diagnosis of hyperacute cerebral infarction.In this study,the combination of MR diffusion(DWI)and perfusion imaging(PWI)in the diagnosis of ischemic penumbra in hyperacute cerebral infarction is reviewed.
