Radiologists, AI systems show differences in breast-cancer screenings, new case study finds

by New York University In these three examples of soft tissue lesions, the images are unperturbed on the left column and blurred on the right column. The AI system was sensitive to the blurring, while the radiologists were not. This showed that the AI system relies on details in soft tissue lesions that are considered...
