  2. aBased on 286 studies with the following primary research areas: artificial intelligence (n = 38), breast (n = 16), cardiac (n = 32), chest (n = 20), computed tomography (n = 4), emergency (n = 1), gastrointestinal–abdominal (n = 21), head–neck (n = 6), magnetic resonance (n = 3), multisystem (n = 1), musculoskeletal (n = 18), neuroradiology (n = 46), nuclear medicine (n = 51), oncology (n = 2), pediatric (n = 2), ultrasonography (n = 2), urogenital (n = 17), and vascular (n = 6)
  3. bStudies with artificial intelligence as research area were significantly associated with increased workload
  4. cBased on 26 individual journals with a median impact factor of 5.061 (range: 2.687–33.752)
  5. dPer unit increase in impact factor
