7T DTI in Mild Chronic Traumatic Brain Injury: Assessment of the Superior Longitudinal Fasciculus and Cingulum Bundle

Abstract

Introduction: Mild chronic traumatic brain injury (TBI) causes behavioral deficits without changes to standard anatomical MRI. The event of mild TBI causes axonal shearing which disrupts the highly organized bundles of nerve fibers. Diffusion tensor imaging (DTI) is sensitive to water diffusion along or across these fiber bundles. Quantitative parameters of… (More)
