Researchers have developed a weakly supervised multiple instance learning approach for automated scoring of ulcerative colitis activity using foundation models. This method leverages case- and slide-level labels to predict the five-grade Nancy histological index, addressing the time-consuming and variable nature of manual grading. The study evaluated various foundation models on a multicenter dataset, finding that Virchow2 performed well and that ensembling improved prediction accuracy. AI
