摘要
目的 研究弥漫性轴索损伤的MRI特征。方法 本文收集临床确诊的DAI共 35例 ,均作了常规MRI检查。结果 35例中共发现 72个病灶 ,其中包括大脑白质 40灶 ,小脑 2灶 ,基底节区 2灶 ,胼胝体 1 2灶 ,大脑脚 1 2灶 ,脑桥 2灶 ,延髓 2灶。MRI征象为T1WI小片状或条状低信号 ;T2 WI为高信号。结论 MRI对评价DAI很有价值 ,T2
Objective To study the MRI features of diffuse axonal injury. Methods 35 cases of DAI were reported,the MRI examination were made in all of 35 cases. Results Totally 72 lesions were found in 35 cases. In which there were 40 lesions in cerebral white matter,3 in cerebellum,12 in cerebral peduncle,2 in pons,2 in medulla oblongata.The features were patchy or cord like,slightly hypointense signal in T 1WI,and hyperintense signal in T 2WI. Conclusion MRI has great value in assement of DAI T 2WI was important in the diagnosis of DAI. [
