Diffusion-tensor imaging has been shown to be sensitive
to diffuse axonal injury that is not observed using
structural MRI. The locations of DTI-observed injury
vary considerably between subjects, with the result that
group-wise analyses indicate few associations with
cognitive outcome. In this study maps representing the
probability of tissue injury are generated, for a group
of subjects with mild to moderate traumatic brain injury
and association of summary measures with neurocognitive
measures are evaluated.
