目的研究MRI在诊断弥漫性颅脑 轴索损伤中的临床应用价值，为今后临床 诊断提供参考和借鉴，提高对弥漫性颅脑 轴索损伤的诊断水平。方法 选取2010年 1月-2014年10月期间我院收治的76例弥漫 性颅脑轴索损伤患者为研究对象，根据诊 断方式的不同分为两组，对照组患者采 用CT进行检查，观察组患者采用MRI进行 检查，比较两组患者的诊断结果。结果 观察组对于脑深部区域、非出血病灶及 出血病灶的检出数量明显高于对照组，p ＜0.05；观察组的诊断敏感度要高于对照 组，p＜0.05，差异具有统计学意义。结 论 CT和MRI对弥漫性颅脑轴索损伤的诊断 都具有重要的临床诊断价值，但是MRI的 诊断敏感度要高于CT，尤其是对脑内非出 血病灶和深部病灶的敏感度要高于CT，和 CT检查技术相比，具有更明显的优势，值 得在临床实践中广泛的应用和推广。

Objective To study clinical application value of MRI in the diagnosis of diffuse cerebral axonal injury,and provide a reference for clinical diagnosis in the future,also improve the diagnosis level of diffuse cerebral axonal injury. Methods Seventy six patients with diffuse cerebral axonal injury patients admitted by this hospital from January, 2010 to October, 2014 were selected as research subjects, who were divided into two groups according to different methods of diagnosis, patients in the control group were subject to CT examination, and patients in the observation group were subject to examinations with magnetic resonance imaging (MRI), diagnosis results of patients in two groups were compared. Results The detection quantity of deep cerebra area, non-bleeding lesions and bleeding lesions of patients in the observation group were significantly higher than that of patients in the control group, p<0.05, and the diagnosis sensitivity of patients in the observation group was higher than that of patients in the control group, p<0.05, and the difference was statistically significant. Conclusions Both CT and MRI pose important clinical diagnostic value in the diagnosis of diffuse cerebral axonal injury, but the diagnosis sensitivity of MRI is higher than that of CT, especially the sensitivity of non-bleeding cerebral lesions and deep lesions is higher that of CT, and it delivers more significant advantages when compared to CT examination technology, being worthy of wide application and promotion in clinical practices.
