ABSTRACT
In the acute clinical setting both computed tomography (CT) and conventional magnetic resonance imaging (MRI) are established imaging modalities to rule out severe complications resulting from traumatic brain injury (TBI) such as skull fracture, intracranial hemorrhage, and brain edema. However, when applied to mild traumatic brain injury (mTBI) only about 10% of CT scans and 30% of MR scans reveal abnormalities such as subdural or subarachnoidal hemorrhage.1-3 Moreover, conventional CT and MRI have proven insensitive to more subtle changes in the brain such as
