| 摘 要： | 目的：探讨弥漫性轴索损伤（DAI）的CT、常规MRI序列和磁敏感加权成像（SWI）表现与诊断价值。方法：回顾分析42例DAI患者的影像资料，分析、比较CT、MRI和SWI的信号特征及脑内病灶显示率。结果：SWI显示病灶最多、最敏感；脑CT扫描次之；常规MRI序列敏感性差，只有部分病灶显示。结论：CT、MRI和SWI对DAI早期诊断、治疗及评价预后具有重要参考价值，SWI是诊断DAI最有效的首选影像学检查方法。

| Abstract: | Objective： To investigate the diffuse axonal injury （DAI） of the CT, conventional MR/sequences and susceptibility weighted imaging （SWI） features and diagnostic value. Methods： Retrospective analysis of 42 cases of DAI in patients with image data, analysis, comparison CT, MRI, and SWI signal characteristics and brain lesions display rate. Results： SWI showed lesions up to the most sensitive; brain CT scan, followed by; poor sensitivity of conventional MRI sequences, only some of the lesions appear. Conclusion： CT, MRI, and SWI of DAl early diagnosis, treatment and prognostic evaluation of important reference value, SWI DAI is the most effective diagnostic imaging method of choice. |
