RT Journal Article SR Electronic T1 Corpus Callosum Diffusion Anisotropy Correlates with Neuropsychological Outcomes in Twins Disconcordant for Traumatic Brain Injury JF American Journal of Neuroradiology JO Am.

YR 2006 UL http://www.ajnr.org/content/27/4/879.abstract AB SUMMARY: 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.
