摘 要: | 目的:探讨脑弥漫性轴索损伤(DM)MRI特征以及诊断价值。材料与方法:21例病人均有MRI检查,其中:13例病人还有CT检查。分析21例DM病人的临床资料和影像学特点,进行回顾性分析。结果:DM发生于以下6个部位:胼胝体5例;皮髓交界处6例;脑白质7例;脑干6例;基底节5例;小脑3例;脑室旁5例。多发病灶共18例。21例DM伤者中18为交通伤。本组DM伴其他脑伤者16例。CT上难以发现病灶的小脑、脑干和胼胝体等处8/21,MRI均可以清晰显示。结论:MRI对发现DM价值较大。CT上难以发现病灶的小脑、脑干和胼胝体等处,MRI也可以清晰显示。

Abstract: | Purpose: To Study the value of Mill to the diagnosis of diffuse axonal injury (DAI). Meterials and Methods: 21 cases clinicallly proved and rtetospectively analysed (21 cases had Mill examinaltion, 13 Mill and CT examinations). Results: The MRI findings these 6 places change: corpus callomsum (5), cortex-medulla conjunction (6), white matter (7), brain stem (6), basal nodal (5), cerebellum (3), hemorrhage in the brain venh4cles (5), multiple change (18), 17/21 are traffic injury, complicated change 12/21. Conclusion: MRI examinations have a high value to DAI diagnosis, is very important to the early diagnosis of DAI. |
