MonteRET: AI Agent Enhancing Multimodal LLMs with Multi-granularity Knowledge Retrieval for Chest CT Report Generation

arXiv cs.CL · 6 hours ago

MonteRET is an AI system that generates chest CT reports by combining whole-volume understanding with region-level anatomical analysis, using retrieved medical knowledge to refine outputs. The model was trained on 24,128 CT scans from RadGenome-ChestCT and evaluated on 1,564 test scans plus 82 external scans, showing improvements in report quality and semantic similarity with particular gains in recall of findings. The approach reduces omitted clinical findings and received positive evaluation from radiology residents compared to existing methods.
