False-positive and false-negative cases found by the algorithm in the validation set. (a) A supine abdominal radiograph of a 15-month-old boy without intussusception. One radiologist and the algorithm reported false-positive results, while the other three radiologists reported true-negative results. (b) A supine abdominal radiograph of a 10-month-old boy with intussusception. One radiologist and the algorithm reported false-negative results, while the other three radiologists reported true-positive results. (c) A supine abdominal radiograph of a 29-month-old boy with intussusception. All of the four radiologists and the algorithm reported false-negative results.
