Can AI help rule out ‘unremarkable’ chest x-rays?
Example of triage of no change in a pair of chest radiographs in the emergency department. (A) Baseline posteroanterior chest radiograph in a 63-year-old female patient shows a small amount of left (L) pleural effusion and partial atelectasis of the right middle lobe. (B) Follow-up posteroanterior chest radiograph obtained in the same patient 1 day later shows no significant change. (C) Gradient-weighted class activation map shows the algorithm determined no change in the image pair, without relevant highlighting, as the highlighted area is located over the gastroesophageal junction.

Representative injuries in patients from the mass casualty incident of October 7, 2023. (A) Axial CT scan at the pelvic level in a 34-year-old male patient shows multiple shrapnel fragments in the pelvis, resulting in fractures of the pelvic bones and lumbar vertebrae (not visible on this image). (B) Coronal reconstruction of a head CT scan in a 20-year-old male patient shows penetrating trauma to the left eyeball with a retained bullet in the orbital cavity. (C) Radiograph of a fetus delivered by emergency cesarean section from a critically injured mother shows a left pneumothorax and catheter in place. (D) Radiograph in a 25-year-old female patient shows a comminuted fracture in the tibial metaphysis with fragment displacement and multiple bony fragments in the surrounding soft tissues.

AI model detects achalasia on chest x-rays
By Will Morton
Currently, few noninvasive tests are available for diagnosing the swallowing condition.
September 18, 2025
Saliency maps using Grad-CAM++ (E and H) show the model’s point of interest in chest radiographs (C and F) of patients with achalasia. The model’s point of interest is highlighted with red, yellow, and green. In both the upper and lower panels (E and H), the point of interest is located in a region around the upper esophagus that corresponds to an air esophagogram and/or air-fluid level in the esophagus in the barium esophagogram (D and G).
