Multimodal Neurodiagnostic Imaging of Traumatic Brain Injury and Post-Traumatic Stress Disorder (SANIC)
The purpose of this study is to determine whether the brains of persons with and without traumatic brain injury differ in a meaningful way when advanced technology images of the brain are taken using three newer technologies that visualize the brain using a combination of external/internal magnetic fields and radioactive tracers (molecules that emit detectable particles). The hope is that the results of this study will validate tools (help prove that diagnostic tools actually detect disease) for the diagnosis and treatment of traumatic brain injuries (TBI).

'Normal' appearing brain is often not normal when imaged with advanced neuroimaging techniques. It has been advocated that a battery of neurological assessments (including MEG) be developed to assess mild traumatic brain injury (TBI) and studies have shown that somatosensory evoked fields in severe TBI can serve as a measure of cortical function in comatosed TBI patients. Functional neuroimaging techniques such as PET and fMRI may reveal abnormalities in areas considered 'normal' on traditional MRI. Most significantly, advanced functional neuroimaging may enable customized neurorehabilitation planning with more efficient use of resources.
The study aim is to compare healthy brains, civilian TBI brains, and combat-related TBI to identify correlations between abnormal imaging parameters with neurorehabilitation potential utilizing advanced neurological imaging.
The study hypothesis states Severity of Traumatic Brain Injury (TBI) and Post-traumatic Stress Disorders (PTSD) can be detected and quantified using a multimodal battery of neurodiagnostic imaging techniques (MEG, PET/CT, 3 Tesla-MRI w/ DTI and fMRI) and rehabilitation potential can be predicted in the post acute phase.
