Abstract Purpose In the adult emergency department of a university hospital, we investigated the frequency of major discrepancies between the preliminary reports by radiology residents and the final reports by certified radiologists. Materials and Methods Based on CT and MRI scans obtained between December 2016 and November 2019, we selected cases with diagnoses or treatment plans that could be changed due to discrepancies between preliminary and final reports and classified them by the type of discrepancy. We also examined the distributions of the major discrepancies and stratified them by residents' working time zone, experience, and subspecialty. Results Based on the 72137 preliminary reports evaluated, 1348 tests (1.9%) showed major discrepancies. Most of the major discrepancies were false negatives (72.0%), followed by misdiagnosis (26.3%) and false positives (1.7%). Acute findings (87.2%) were more common than non-acute findings (12.8%). The major discrepancy rate increased toward the second half of the 24-hour shift, with the highest rate of 2.9% occurring between 2 am and 4 am. The major discrepancy rate did not vary with experience, and it varied from 0.6% to 4.5% for each subspecialty. Conclusion The major discrepancy rate was less than 2%, and it increased with longer working hours during a 24-hour shift. 목적 대학병원 성인응급실에서 영상의학과 전공의 가판독과 전문의 최종 판독 간에 불일치가 발생한 빈도를 조사하고, 이 발생률에 영향을 미칠 수 있는 요인을 살펴보았다. 대상과 방법 2016년 12월부터 2019년 11월까지 성인응급실에서 촬영된 전산화단층촬영과 자기공명영상 검사 중, 전공의 가판독과 전문의 최종 판독 간에 불일치로 인해 환자의 진단이나 치료 계획이 변경될 수 있는 경우를 중대한 불일치로 정의하고, 이를 유형별로 분류하였다. 이후 전공의 근무 시간대, 응급실 근무 경력, 세부 분야별로 중대한 불일치 발생률의 분포를 살펴보았다. 결과 총 72137건의 가판독 중 중대한 불일치를 보인 검사는 총 1348건(1.9%) 이었다. 중대한 불일치의 유형으로는 위음성(72.0%)이 가장 많았고, 오판(26.3%), 위양성(1.7%) 순이었다. 또한 급성 소견의 중대한 불일치(87.2%)가 비급성 소견의 중대한 불일치(12.8%)보다 많았다. 중대한 불일치 발생률은 24시간 교대 근무 후반부로 갈수록 증가하였으며, 새벽 2시부터 4시 사이가 2.9%로 가장 높았다. 전공의의 응급실 근무 경력에 따른 발생률 차이는 없었고, 세부 분야별 발생률은 0.6%-4.5%로 다양했다. 결론 가판독과 최종 판독 간에 중대한 불일치 발생률은 2% 미만이었고, 24시간 교대 근무 후반으로 갈수록 증가하였다.
