目的探究MRI弥散加权(DWI)对急性脑梗死的诊断价值。方法对我院2009年1月到2012年6月之间发病时间在6h内的急性脑梗死的64例患者采取急诊MRI与DWI的检查。分析采取MRI弥散加权诊断急性脑梗死的特异性和敏感性等。结果通过临床诊断,其中采取MRI弥散加权诊断与临床中最终的诊断相符合,而且特异性和敏感性均达到了100.0%,而常规的MRI诊断的敏感性明显的低于DWI的诊断情况,比较具有明显的差异,P<0.05,统计学有意义。结论对于急性脑梗死患者采取MRI弥散加权诊断具有较好的诊断效果,具有较高的敏感性和特异性,在临床诊断中具有重要的研究价值。
Objective To investigate the diagnostic value of MRI diffusion weighted (DWI) in acute cerebral infarction. Methods 64 cases of acute cerebral infarction within 6h after onset of illness between January 2009 and June 2012 in our hospital were examined by emergency MRI and DWI. To analyze the specificity and sensitivity of using MRI diffusion weighted diagnosis of acute cerebral infarction. The results of clinical diagnosis, which took MRI diffusion-weighted diagnosis and clinical diagnosis of the final line, and the specificity and sensitivity reached 100.0%, while the sensitivity of conventional MRI diagnosis was significantly lower than the diagnosis of DWI, compared There was a significant difference, P <0.05, statistically significant. Conclusion The diagnosis of acute cerebral infarction patients with MRI diffusion-weighted diagnosis has a good effect, with high sensitivity and specificity, in clinical diagnosis has important research value.
