摘要
目的:分析弥漫性颅脑轴索损伤应用CT与MRI诊断的价值。方法:选择2014年5月-2017年5月在我院治疗的128例DAI患者临床资料,按诊断方式不同分2组,各组64例,对照组予CT诊断,观察组予MRI诊断,比较两组颅内异常诊断及脑内病灶检出情况。结果:观察组MRI检出脑室出血、蛛网膜下腔出血、硬膜外血肿、弥漫性脑肿胀、脑内出血性病灶及非出血性病灶异常率26.56%、43.75%、29.69%、45.31%、57.81%、68.75%均比对照组CT检出率高(P<0.05);观察组大脑皮质下、小脑部位病灶的MRI检出率79.69%、34.38%均比对照组CT检出率高(P<0.05);观察组MRI阳性检出率96.88%比对照组CT检出高,阴性检出率3.13%比对照组CT检出低(P<0.05)。结论:与CT诊断比,MRI诊断可提高DAI患者颅内异常检出率,有效检出大、小脑及基底节部位病灶,且诊断敏感性高,具较高的弥漫性颅脑轴索损伤诊断价值。
Objective： To analyze the value of CT and MRI in the diagnosis of diffuse axonal injury. Methods：The clinical data of 128 DAI patients who had received treatment in our hospital between May 2014 and May 2017 were selected; according to the different diagnostic methods applied,these patients were divided into 2 groups,with 64 cases in each group： the control group received CT for diagnosis,whereas the observation group was given MRI for diagnosis. The intracranial abnormity diagnosed and brain lesions detectioned in the two groups were compared. Results： The abnormity rates detected by MRI for intraventricular hemorrhage,subarachnoid hemorrhage,epidural hematoma,diffuse cerebral edema,intracranial hemorrhagic lesions and non-hemorrhagic lesions in the observation group were respectively 26. 56%,43. 75%,29. 69%,45. 31%,57. 81% and 68. 75%,all shown to be higher than those detected by CT in the control group（ P〈0. 05）; the detection rates for lesions under cerebral cortex and cerebellum by MRI in the observation group were respectively79. 69% and 34. 38%,both higher than those detected by CT in the control group（ P〈0. 05）; the positive detection rate by MRI in the observation group was 96. 88%,higher than that by CT in the control group,and the negative detection rate in the former group was 3. 13%,lower than that by CT in the control group（ P〈0. 05）. Conclusion： Compared with CT diagnosis,MRI is with higher sensitivity and diagnostic value for diffuse axonal injury,which can improve the detection rate of intracranial abnormalities in DAI patients,and effectively detect the lesions under cerebral cortex and cerebellum,and basal ganglia lesions.
