Purpose Growing numbers of patient with advanced imaging being transferred to trauma centers has resulted in increased numbers of outside CT scans received at trauma centers. This study examines the degree of agreement between community radiologists’ interpretations of the CT scans of transferred patients and trauma center radiologists’ reinterpretation. Methods All CT scans of emergency transfer patients received over a 1 month period were reviewed by an emergency radiol- ogist. Patients were classified as trauma or non-trauma and exams as neuro or non-neuro. Interpretive discrepancies between the emergency radiologist and community radiologist were classified as minor, moderate, or major. Major discrepancies were confirmed by review of a second emergency radiologist. Discrepancy rates were calculated on a per-patient and per exam basis. Results Six hundred twenty-seven CT scans of 326 patients were reviewed. Major discrepancies were encountered in 52 (16.0%, 95% CI 12.2–20.5) patients and 53 exams (8.5%, 95% CI 6.5–10.5). These were discovered in 46 trauma patients (21.6%, 95% CI 16.4–27.9) compared to six non-trauma patients (5.3%, 95% CI 2.2–11.7) (P < 0.001). A significant difference in the major discrepancy rate was also found between non-neuro and neuro exams (12.4 vs 3.3%, respectively, P < 0.001), primarily due to
