摘要
目的：评价磁共振弥散加权成像（DWI）在诊断急性脑梗塞中的应用价值。方法：回顾性分析发病2~24h内急性脑梗塞病人26例,先行CT平扫,后行常规MR成像及DWI检查,然后进行对比分析。结果：超急性期（2~6h）脑梗塞6例,CT检查阴性,其在SE-T2WI及FLAIRT2WI序列上均未见明显显示,而DWI均显示了不同程度高信号;急性期（6~24h）脑梗塞20例,只有6例CT提示有较明确新鲜病灶。DWI对急性期脑梗塞的显示优于常规MR序列。结论：DWI对超急性期、急性期脑梗塞具有高度的特异性和敏感性,能做出准确诊断。
Objective： to study the roles of isotropic diffusion weighted imaging in diagnosing early cerebral infarction.Methods：to analysis the patients with cerebral infarction （2-24h） of 26 people for CT and MR DW1 and conventional MR （T1WI,T2W1,FIair）,then to analysis and compare.Results：6 eases of super acute cerebral infarction patients（〈6h）DWI performance for high signal, CT and SE-TzWI or FLAIR-T2WI are not shown lesions, only 6 cases CT can shown in 20 patients of acute cerebral infarction patients（6-24h）. DW1 is far superior to con- ventional MR （T1WI,T2WI,Flair）.Conclusion：DW1 have greater sensitivity for acute and hyperacute cerebral in- farction and can accurately detect.
