CheXpercept: A Benchmark for Evaluating Expert-Level Lesion Perception in Chest X-rays

Geon Choi, Hangyul Yoon, Nalee Kim +5

The evaluation of vision-language models (VLMs) for chest X-ray (CXR) analysis has largely been limited to disease-presence classification without visual grounding. Such evaluation…

CXReasonAgent: Evidence-Grounded Diagnostic Reasoning Agent for Chest X-rays

Hyungyung Lee, Hangyul Yoon, Edward Choi

Chest X-ray plays a central role in thoracic diagnosis, and its interpretation inherently requires multi-step, evidence-grounded reasoning. However, large vision-language models (L…
