  • Diagnostic Value of Diffusion Weighted Imaging in Acute Cerebral Infarction

    【摘要】 目的 探讨低场磁共振弥散加权成像(DWI)诊断急性脑梗死的价值。 方法 2007年7月-2009年9月对48例脑梗死患者行常规MRI扫描和DWI,分析不同时期脑梗死的DWI表现。 结果 在发病的超急性期及急性期,DWI病灶显示率均为100.0%,T2WI病灶显示率分别为37.5%、73.7%、100.0%。 结论 低场DWI对急性脑梗死的诊断准确率高,明显优于常规MRI。【Abstract】 Objective To investigate the diagnostic value of diffusion weighted imaging (DWI) in acute cerebral infarction. Methods From July 2007 to September 2009, 48 patients with ischemic stroke underwent conventional MRI and DWI, and the characteristics of DWI were analyzed. Results Abnormal DWI signals were displayed in all patients at hyperacute stage or acute stage, abnormal T2WI signals existed in 37.5%, 73.7%, and 100.0%, respectively. Conclusion DWI in low field MR is highly accurate in diagnosing acute cerebral infarction, which is superior to conventional MRI.
