  Veterans with mild traumatic brain injury (mTBI) have reported auditory and
visual dysfunction that persists beyond the acute incident. The etiology behind
these symptoms is difficult to characterize with current clinical imaging.
These functional deficits may be caused by shear injury or micro-bleeds, which
can be detected with special imaging modalities. We explore these hypotheses in
a pilot study of multi-parametric MRI. We extract over 1,000 imaging and
clinical metrics and project them to a low-dimensional space, where we can
discriminate between healthy controls and patients with mTBI. We also show
correlations between the metric representations and patient symptoms.
