高功能孤独症患儿全脑白质纤维的弥散张量成像研究

Objectlve To analysis the changes of white matter fiber in autistic disorder.Methods Diffusion tensor imaging(DTI)data were obtained from 18 autistic children and 10 age-,sex-and intelligent quotient matched normal controls.Voxel-based analysis Was applied to assess the fractional anisotropy(FA)in cerebral tissues.Results Compared with the controls,the FA values in autistic children were significantly decreased in the white matter of right inferior frontal gyrus,left middle frontal gyrus and right inferior temporal gyms,and increased in the white matter of left superior parietal lobule(P＜0.001).Furthermore.the white matter changes on left middie frontal gyrus were significandy correlated with the scores of Childhond Autism Rming Scale(CARS)in autistic children(r=-0.63,P=0.005).Conclusion The white matter integrity is probably disconnected in many brain regions in children with autistic disorder.

高功能孤独症患儿全脑白质纤维的弥散张量成像研究

目的 分析高功能孤独症患儿的全脑白质纤维的完整性.方法 对18例高功能孤独症患儿(病例组)以及10名年龄、性别、智商与病例组相匹配的健康儿童(对照组)进行全脑弥散张量成像(DTI)测量;应用基于体素的分析方法,比较两组全脑各向异性分数(FA)的差异.使用Spearman相关分析,分析病例组各感兴趣区FA值与儿章期孤独症评定表(CARS)总分及各项目之间的关系.结果 与对照组相比,病例组右侧额下回、左侧额中回及右侧颞下回邻近白质的FA值低(分别为0.67±0.10、0.57±0.09、0.50 ±0.12),左顶上小叶邻近白质的FA值高(0.55±0.15;P<0.001).病例组左额中回邻近白质的FA值与CARS中的与非生命物体的关系的得分呈负相关(r=-0.63,P=0.005).结论 高功能孤独症患儿多个部位的脑白质纤维的完整性受到破坏.
