目的对比SWI序列对弥漫性轴索 损伤敏感性和常规TSE序列、SE序列检测 结果。方法 对2013年1月至2013年12月我 院收治的弥漫性轴索损伤患者37例的临 床资料进行统计分析。结果 37例弥漫性 轴索损伤患者常规TSE序列、SE序列和SWI 序列病灶均较多地分布在皮髓质交界区， 分别占总数的48.55%、40.39%、42.09%； 其次为白质、基底节、胼胝体；最后为 小脑、脑干。病灶数目分别为3.73、 5.49、19.65，SWI序列弥漫性轴索损伤 病灶数目显著多于常规SE序列、TSE序列 (P<0.05)；SWI序列弥漫性轴索损伤检出 率81.08%(30/37)显著高于常规SE序列、 TSE序列27.03%(10/37)、32.43%(12/37) (P<0.05)。结论 SWI序列对弥漫性轴索 损伤检测敏感性比常规TSE序列、SE序列 高，值得在临床推广。

Objective To compare the sensitivity results of SWI sequence and conventional TSE sequences, SE sequence in the detection of diffuse axonal injury. Methods The clinical data of 37 cases of diffuse axonal injury patients in our hospital from January 2013 to December 2013 were statistically analyzed. Results The conventional SE sequences, TSE sequences and SWI sequence lesions of 37 cases of patients with diffuse axonal injury were more distributed in cortex and medulla region, accounting for 48.55%, 40.39%, 42.09%of the total, respectively; followed by white matter, basal ganglia the corpus callosum; finally the cerebellum, brainstem. The number of lesions were 3.73, 5.49, 19.65, the number of diffuse axonal injury lesions of SWI sequence was significantly more (P<0.05); the detection rate of diffuse axonal injury 81.08%(30/37) was significantly higher than conventional SE sequences, TSE sequence 27.03%(10/37), 32.43% (12/37) (P<0.05). Conclusion The sensitivity of SWI sequence in the detection of diffuse axonal injury is higher than conventional TSE sequences, SE sequence, so is worthy of promotion in the clinical.
