From: Diagnosis of nasal bone fractures on plain radiographs via convolutional neural networks
Examples of false positive images (normal nasal bone radiographs incorrectly diagnosed as fractures by the DL model). (a) The heatmap focuses on the angulated nasal bone in the left lateral view (right); (b) the heatmap focuses on nasal area narrowly separated from adjacent facial bones in the left lateral view (right); (c) the heatmap focuses on linear radiolucent line besides the nasal bone in the left lateral view (right); (d) the nasal bone is small and thin in the right lateral view (left) and faintly visible in the left lateral view (right). The predicted probabilities of fractures by the DL model are shown for each patient.
