【摘要】 目的 探讨磁敏感加权成像(SWI)对弥漫性轴索损伤(DAI)的诊断价值。方法 对43例临床可疑DAI病例行常规MR(TSE、FLAIR、DWI)及SWI检查，分别检测各方法所示患者脑内出血灶数量。结果 SWI共显示1132个出血灶，较CT、常规MR序列显示更多。结论 SWI能非常敏感地检出外伤后弥漫性轴索损伤患者脑内的小出血灶，可以进一步提高对弥漫性轴索损伤的诊断正确率，帮助临床医生早期诊断、治疗。

【Abstract】 Objective To study the diagnostic value of susceptibility weighted imaging sequence in diffuse axonal injury. Methods 43 patients with diffuse axonal injury carried out diagnosis of conventiona MR imaging and SWI sequence. Results SWI described 1132 lesions in all, much more than the other image sequences. Conclusion SWI sequcences has higher sensibility than other sequences in diagnosis of diffuse axonal injury.
