Twenty patients admitted for minor or moderate closed-head injury were studied to investigate the relationship between magnetic resonance imaging (MRI) and neurobehavioral sequelae. The MRI scans demonstrated 44 more intracranial lesions than did concurrent computerized tomography (CT) in 17 (85%); most of these located frontal temporal regions. Estimates lesion volume based on frequently greater with CT; however, disclosed no additional that required surgical evacuation. Neuropsychological assessment during initial hospitalization revealed deficits lobe functioning memory related size localization as defined by MRI. Follow-up neuropsychological testing at 1 month (13 cases) 3 months (six marked reduction paralleled improvement cognition memory. These findings encourage further investigation prognostic utility clinical management rehabilitation mild head injury.
