Diffusion imaging shows abnormalities after blunt head trauma when conventional magnetic resonance imaging is normal.
The investigation and management of patients after head injury must include the accurate and complete identification of cerebral damage. Using diffusion tensor imaging, abnormalities of diffusion in patients with head injuries and unremarkable MRI have been shown for the first time.
