| 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.

| Abstract: | 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. |
