  • In a comprehensive dataset from 3,652 patients across 20 centers in eight countries, an ultrasound-based AI model shows robust performance across centers, ultrasound systems, 58 histological diagnoses and patient age groups and reduced referral to experts by 63% in a retrospective triage simulation.
