This study aims at comparing the performances of routine radiological interpretation and artificial intelligence (AI) in the detection of skeletal lesions. We retrospectively evaluated all radiographs performed after a recent trauma during 3 consecutive months in an imaging group.  Each examination was analyzed by the AI and its results were compared to those of the radiologists’ reports. In case of discrepancy, the examination was reviewed by a senior skeletal radiologist to settle on the presence of fractures, dislocations, elbow effusions, and focal bone lesions (FBL).  A total of 4774 exams were included in the study.  Lesion-wise sensitivity was 73.7% for the radiologists’ reports vs. 98.1% for the AI (+24.4 points) for fracture detection, 63.3% vs. 89.9% (+26.6 points) for dislocation detection, 84.7% vs. 91.5% (+6.8 points) for elbow effusion detection, and 16.1% vs. 98.1% (+82 points) for FBL detection. The specificity of the radiologists’ reports was always 100% whereas AI specificity was 88%, 99.1%, 99.8%, 95.6% for fractures, dislocations, elbow effusions, and FBL respectively. The NPV was measured at 99.5% for fractures, 99.8% for dislocations, and 99.9% for elbow effusions and FBL.
