Physician involvement and research quality in chest X-ray foundation models

Chest radiograph foundation models (FMs) are developing rapidly, yet their reporting practices remain unknown. We systematically reviewed 41 FMs published through 3/24/2025 and assessed technical trends, CLAIM adherence, artifact sharing, and physician co-authorship. Transformers and large language model components were increasingly common, while model sharing was limited. Physician co-authorship was associated with higher CLAIM adherence and more frequent fairness discussion, supporting clearer reporting standards for clinically oriented AI research.
