Generating Reports or Repeating Templates? Measuring and Mitigating Template Collapse in 3D CT Report Generation arXiv:2605.30984v1 Announce Type: new Abstract: Modern 3D medical vision-language models (VLMs) can generate fluent radiology-style text while exhibit critically low pathology detection and output diversity, collapsing to generic templates that under-report rare yet critical findings. We identify this failure mode as Template Collapse. This failure stems from the unique constraints o
