摘要:

弥散张量成像中的各向异性分数值可定量脑损伤时神经纤维的一致性,其值越高,神经纤维损伤程度越小。鉴于此,实验假设弥散张量成像能评估亚低温疗法治疗弥漫性轴索损伤的效果。将弥漫性轴索损伤患者102例随机分为两组,分别进行常温治疗及亚低温治疗。发现亚低温组患者治疗2个月后的改良Rankin量表评分值显著低于常温组,治疗前后亚低温组患者各感兴趣区的平均各向异性分数差值约为常温组的1.32-1.36倍。弥散张量成像定量评估结果说明,亚低温疗法治疗弥散性轴索损伤疗效较好,验证了假设。

Abstract:

Fractional anisotropy values in diffusion tensor imaging can quantitatively reflect the consistency of nerve fibers after brain damage, where higher values generally indicate less damage to nerve fibers. Therefore, we hypothesized that diffusion tensor imaging could be used to evaluate the effect of mild hypothermia on diffuse axonal injury. A total of 102 patients with diffuse axonal injury were randomly divided into two groups: normothermic and mild hypothermic treatment groups. Patient’s modified Rankin scale scores 2 months after mild hypothermia were significantly lower than those for the normothermia group. The difference in average fractional anisotropy value for each region of interest before and after mild hypothermia was 1.32–1.36 times higher than the value in the normothermia group. Quantitative assessment of diffusion tensor imaging indicates that mild hypothermia therapy may be beneficial for patients with diffuse axonal injury.
