Résumé
Background
Cross-domain chest radiograph report generation may produce formally valid reports that are nevertheless repetitive, weakly case-specific, or missing clinically relevant findings. These failures can be missed when evaluation relies on a single language-overlap or clinical-label score.
Objective
This study aimed to evaluate cross-domain report generation with a bidirectional layered audit, characterize direction-specific and end point-specific failure profiles under a composite training-side control and 3 decoding policies, and explore whether selected audit dimensions remained informative for a contemporary medical vision language model.
