| 摘 要： | 目的探讨磁共振弥散加权成像（DWI）对脑梗死分期的诊断价值。方法对163例脑梗死患者的常规MRI、液体衰减翻转恢复（FLAIR）及DWI图像进行比较研究分析。结果超急性、急性和亚惠性脑梗死在DWI上均表现为高信号。在避急性脑梗死弥散加权像可显示T2加权像不能显示的病灶，在T2WI及FLAIR加权像可显示的病变中，弥散加权像可更清楚更全面地显示病灶。结论DWI对诊断超急性脑梗死十分敏感，结合其他序列能时脑梗死做出明确分期。

| Abstract: | Objective To investigate the diagnostic value of MR diffusion imaging in the various stages of brain infarction. Methods 163 cases with cerebral infarction were analyzed in this study in regular MRI FLAIR and DWI imaging. Results Super-acute, acute and sub-acute cerebral infarction on DWI were displayed superior signa, super-acute cerebral infarction diffusion imaging can display case that T2WI image can't, diffusion imaging can displayed much clearly and completely than that in cases displayed with T2WI and FLAIR. Conclusion DWI are sensitivity in diagnosing super-acute cerebral ischemia and if combined with T2WI and FLAIR, it can distinguish the various stages of brain infarction. |
