【摘要】 目的 探讨DAI的临床诊断预后及影像学改变。方法 取本院自2002年5月～2005年8月收治的38例DAI病例，分析DAI的影像学诊断及临床预后。结果 DAI是颅脑损伤患者最重要的致残病因，个别DAI患者临床并无昏迷表现。结论 急性脑肿胀提示严重的预后不良，核磁在DAI的诊断中明显优于CT，部分早期DAI患者仍可无显著影像学改变。

    【Abstract】 Objective To discuss the clinical imageological diagnosis and prognosis of DAI.Methods To study the 38 patients we have treated since 5 2002 to 8 2005, analysis the imageological diagnosis and clinical prognosis.Results DAI is the capital mutilation etiological factor of head injury.The DAI does not always have clinical coma.Conclusion Acute cerebral edema means severe malaprognosis.MRI is better in effect to diagnosis DAI than CT,some patients of earlier DAI may have no remarkable imageological change.

    【Key words】 DAI(diffuse axonal injury); acute cerebral edema
