MRI results and initial symptoms buoy prediction of outcomes in studies of athletes and emergency department patients.
Some individuals with mild traumatic brain injuries (mTBIs) suffer persistent symptoms. Two studies have now examined predictive factors for prolonged recovery.
Yuh and colleagues analyzed prognostic information from 3T magnetic resonance imaging (MRI) scans performed at a mean of 12 days postinjury and computed tomography (CT) scans performed in the emergency department among participants who had presented for evaluation of an mTBI. Of 1023 screened patients, 135 met study criteria and completed the study (mean age, 40 years; 80% with loss of consciousness [LOC] or posttraumatic amnesia). Of 98 patients with normal CT, 28% had abnormal MRIs (hemorrhagic axonal injury, 23 patients; extraaxial hematomas, 4; contusions, 3). Historical and demo…
