New framework specializes frozen VLMs for endoscopic polyp reporting

Researchers have developed a novel context-fusion framework designed to specialize frozen general-purpose vision-language models (VLMs) for endoscopic polyp reporting. This framework integrates quantitative lesion sizing, standardized Paris classification, and morphological description without altering the VLM's pretrained weights. By employing implicit instruction context via learned specialist tokens and explicit transduction context through retrieved image-report pairs, the system significantly enhances VLM performance on specialized tasks. Experiments on over 2,000 images demonstrated that this lightweight approach, adding minimal trainable parameters, outperformed general-purpose VLMs, task-specific predictors, and weight-adaptation methods.

IMPACT This framework offers a lightweight and effective method for adapting general-purpose VLMs to specialized medical imaging tasks, potentially improving diagnostic accuracy and reporting efficiency.
