An AI Called Percival Found Hidden Diseases Lurking in Routine CT Scans

Penn Medicine's AI model Percival, trained on roughly 400,000 CT scans from 50,000 patients, uncovered traces of atrial fibrillation, chronic kidney disease, pancreatic cancer, cirrhosis and pneumonia hiding in scans ordered for something else. Published in npj Digital Medicine with open-source code, it turns every routine scan into a chance to catch disease early.
