摘　　要：目的:探讨磁共振弥散加权成像(DWI)在急性脑梗塞诊断中的应用价值。方法:选取西安市第四医院自2018年1月~2019年7月的急性脑梗塞病例81例进行回顾性分析,均行CT平扫、磁共振DWI序列扫描,对比分析CT和DWI对不同部位病灶的检出率,对比分析CT和DWI对不同病程患者的检出率。结果:①不同部位急性脑梗塞病灶DWI检出率均高于CT检出率。②超急性期(<6h)患者的DWI检出率(78.57%)显著高于CT检出率(7.14%);急性期(6~24h)患者的DWI检出率(100.0%)显著高于CT检出率(41.79%)。结论:磁共振DWI序列对急性脑梗塞的诊断具有优势,能够为临床治疗提供影像资料和科学指导。Objective:To investigate the value of diffusion weighted imaging(DWI)in the diagnosis of acute cerebral infarction.Methods:81 cases of acute cerebral infarction treated in Xi’an No.4 Hospital from January 2018 to July 2019 were selected for retrospective analysis.All patients underwent CT and DWI examination.The rates of detection were compared between CT and DWI in different disease courses and different areas.Results:①The detection rate of DWI in different areas of acute cerebral infarction was higher than CT.②The detection rate of DWI(78.57%)was significantly higher than CT(7.14%)in the super acute stage(<6 h),and the detection rate of DWI(100.0%)was significantly higher than CT(41.79%)in the acute stage(6~24 h).Conclusion:DWI has advantages in the diagnosis of acute cerebral infarction and DWI can provide imaging data and scientific guidance for clinical treatment.
