摘要
目的探讨常规MRI、CT检查对脑弥漫性轴索损伤的诊断价值。方法搜集经临床证实36例DAI病例的常规MRI、CT检查资料,结合病理文献进行回顾性分析。结果 CT诊断20例,MRI诊断31例。CT、MRI对DAI诊断的阳性率分别为55%(20/36)、86%(31/36),二者相比有统计学差异(P<0.05)。CT检查共发现病灶36个,MR检查(T1WI、T2WI、FLAIR序列)发现病灶分别为97个、115个、147个,CT与MR各序列发现病灶数有统计学差异(P<0.01)。结论常规MRI、CT检查是弥漫性轴索损伤的基本检查方式。常规MRI检查对DAI的诊断价值优于CT检查。
Objective To compare the diagnostic performance of conventional MRI and CT in diffuse axonal injury （DAI）. Methods 36 patients with DAI were included,conventional MRI and CT were analyzed retrospectively, used clinical data or pathological diagnosis as reference standard. Results 20 and 31 patients were diagnosis correctly by CT and MRI respectively, the diagnosis accuracy of MRI was higher than CT（55% vs 86%, P〈0.05）. 36,97,115 and 147 lesions were confirmed in CT,TIWI, T2WI and FLAIR of MR respectively, MRI were better than CT （P〈O.01）. Con- clusion The conventional MRI and CT examination is the basic way of DAI.The conventional MRI is superior to CT in the diagnosis of DAI.
