Patients with minimal head injury (MHI) and a cranial computed axial tomography (CAT) scan positive for the presence of intracranial injury routinely undergo a repeat CAT scan within 24 hours after injury. The value of this repeat cranial CAT scan is unclear in those patients who are neurologically normal or improving.
