目的探讨DWI对急性腔隙性脑梗死的诊断价值。方法98例急性腔隙性脑梗死患者行DWI、T1WI、T2WI检查,分析磁共振图像表现并比较各种检查方法对病灶的检出率。结果98例急性腔隙性脑梗死共发现梗塞病灶178个,DWI、T1WI、T2WI对病灶的检出率分别为100%、48.3%、51.1%。结论DWI对急性腔隙性脑梗死的诊断敏感性高,能准确、可靠地判断病灶的数目、大小及部位,对急性腔隙性脑梗死的诊断具有重要价值。
Objective To investigate the diagnostic value of DWI in acute lacunar infarction. Methods Ninety-eight patients with acute lacunar infarction underwent DWI, T1WI and T2WI examinations, and their magnetic resonance imaging findings were compared. The detection rate of lesions by various examination methods was compared. Results A total of 178 infarcted lesions were found in 98 patients with acute lacunar infarction. The detection rates of lesions on DWI, T1WI and T2WI were 100%, 48.3% and 51.1% respectively. Conclusion DWI is sensitive to the diagnosis of acute lacunar infarction. It can accurately and reliably determine the number, size and location of lesions, which is of great value in the diagnosis of acute lacunar infarction.
