Which Tool Response Should I Trust? Tool-Expertise-Aware Chest X-ray Agent with Multimodal Agentic Learning

This paper introduces TEA-CXA, a tool-expertise-aware chest X-ray agent that utilizes multimodal agentic learning to empirically resolve conflicts between error-prone medical tools by learning their reliability across different query types, while also extending reinforcement learning frameworks to support complex multimodal interactions.

VasGuideNet: Vascular Topology-Guided Couinaud Liver Segmentation with Structural Contrastive Loss

VasGuideNet is a novel Couinaud liver segmentation framework that explicitly leverages vascular topology features encoded via Graph Convolutional Networks and integrated through cross-attention, alongside a Structural Contrastive Loss, to achieve superior anatomical consistency and segmentation accuracy compared to existing state-of-the-art methods.
