| 摘 要： | 目的 探讨CT、MR对脑弥漫轴索损伤(DAI)的诊断价值及与临床、预后关系.方法 回顾性分析经临床确诊的DAI 32例,患者均做了CT检查,其中22行CT及MR检查.结果 32例中共发现237个病灶,其中胼胝体12个,脑干3个,基底节区8个,大脑白质211个,小脑半球3个.85.2%病灶为非出血性病灶,T1W低信号,T2W高信号.损伤部位与患者临床预后、GCS评分有统计学差异(P＜0.05).结论 MR为DAI的临床诊断、预后判断提供了可靠的影像学依据.

| Abstract: | Objective To assess the value of MRI and CT in diagnosis of diffuse axonal injury(DAI)by analyzing manifestations on their images.Mechods 32 cases with clinically-proved DAI were analyzed retrospectively.All these patients had undergone CT,and 22 patients undergone CT and MRI.Results 237 lesions were recognized.The lesions were located in corpus in 12 cases,brain stem in 3 cases,basal nodal region in 8 cases,cerebral white matter in 211 cases,and cerebella in 3 cases.In the study,85.2% of DAI were non-hemorrhagic.There was statistic significance between lesion location and prognosis and score on GCS(P<0.05).Conclusion MRI can provide direct and reliable imaging information for clinical diagnosis and prognosis in DAI. |
