常规和弥散张量磁共振成像研究持续严重的小儿创伤性脑损伤的双胞胎确定减少分数各向异性（FA）在胼胝体的所有区域，特别是后体，喙体，和小脑，相对于健康的cotwin。从喙部，前体，后体和峡部的FA与阅读速度和理解的措施相关;言语工作记忆和数学事实检索分数仅与喙部体FA相关。
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.
