False positive interpretations of the DL algorithm. (a,b) The CR shows radio-opaque letters “ROK ARMY” (arrows) of the shirt at the left middle lung field. (c) The DL algorithm wrongly localised the radio-opaque letters (probability score, 0.348). (d) There is an accidentally included abdominal shield at the lower part of the CR. (e) The DL algorithm wrongly detected the abdominal shield (probability score, 0.684). None of the three observers identified these foreign bodies as lesions.
