Conventional and diffusion tensor MR imaging studies in twins sustaining severe pediatric traumatic brain injury identified reduction in fractional anisotropy (FA) in all regions of the corpus callosum, particularly the posterior body, rostral body, and genu, relative to healthy cotwins. FA from the rostrum, genu, anterior body, posterior body, and isthmus were correlated with measures of reading speed and comprehension; verbal working memory and math fact retrieval scores were correlated only with the rostral body FA.
对遭受严重小儿创伤性脑损伤的双胞胎进行的传统磁共振成像和扩散张量磁共振成像研究发现，与健康的双胞胎相比，胼胝体所有区域，尤其是胼胝体后体、胼胝体嘴部和胼胝体膝部的各向异性分数（FA）降低。胼胝体嘴部、膝部、前体、后体和峡部的FA与阅读速度和阅读理解指标相关；言语工作记忆和数学事实检索分数仅与胼胝体嘴部的FA相关。
