急性期脑梗塞DWI的临床应用

Clinical application of diffusion-weighted imaging (DWI) to acute cerebral infarction

目的探讨DWI在急性期脑梗塞诊断的临床应用价值。方法分析65例临床拟诊为急性期脑梗塞的DWI影像学检查结果,并与出院诊断进行对照性研究。结果在脑梗塞急性期发病6小时内,DWI、CT、常规MRI发现病灶的敏感度分别为98%、33%、57%;DWI诊断有明显的优势。结论在急性期脑梗塞影像诊断中,DWI可作为除外新发脑梗塞的主要手段之一。

Objective To explore clinical role of DWI in acute cerebral infarction. Methods Sixty-five patients suspect for acute cerebral infarction underwent DWI and DWI images were compared to diagnosis upon leaving the hospital. Results Within 6 h after onset,sensitivity of DWI,CT and routine MRI was 98%,33%,and 57% respectively.DWI is far superior to any other means. Conclusion DWI is able to play a principal role in excluding possibility of new onset of cerebral infarction.
