**Abstract:**  
Despite the fact that most CT scans performed on head injured patients are negative, CT remains the “gold standard�? for evaluation of head injury in the Emergency Department.  This study investigates the utility of the *BrainScope One* EEG based classification algorithm to aid in the reduction of unnecessary CT scans in the mild head injured population.  Evaluations were performed on 64 patients (mean age 43.5, 58% male, 98% GCS=15), enrolled in the *BrainScope One* Registry, who sustained closed head injury and were evaluated in the ED at Washington University (mean time since injury 10.1 hours) and were referred for CT scans by standard clinical site practice pathway. Results were compared with those from *BrainScope One* evaluation. In this population of ED patients, the *BrainScope One* decision pathway would have resulted in a 32.8% reduction in the overall number of CT scans referrals compared to the clinical site practice decision pathway.  Importantly, this reduction in CTs was achieved without incurring any false negative cases (100% sensitivity).
