| 摘 要： | 目的：探讨弥散加权磁共振成像（DWI）对急性脑梗死的诊断价值。方法：选取发病〈24h的急性脑梗死患者68例，均行T1WI、T2WI、液体抑制反转恢复（T2-FLAIR）及弥散加权磁共振成像（DWI）检查。结果：DWI、T2-FLAIR、T2WI、TlWI对急性脑梗死诊断准确率分别为100％、79．41％、66．18％、54．41％，有极显著差异。结论：DWI更易于发现病灶，对急性脑梗死尤其是超急性期脑梗死诊断具有明显优势。

| Abstract: | Objective：To study the diffusion-weighted magnetic resonance imaging （DWI） for the diagnosis of acute cerebral infarction. Methods： onset 〈24h 68 patients with acute cerebral infarction were performed T1WI, T2WI, fluid suppressed inversion recovery （T2-FLAIR） and diffusion-weighted magnetic resonance imaging （DWI） checks.Results： The results of DWI, T2-FLAIR, T2WI, TIWI diagostic aecursey of acute cerebral infarction were 100%, 69.12%, 47.06%, 35.29%, a significant difference. Conclusion： DWI lesions are easier to find, especially in acute cerebral infarction in hyperacute cerebral infarction has obvious advantages. |
