New MedGrounder model advances generalised medical phrase grounding

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced MedGrounder, a novel model for generalised medical phrase grounding (GMPG). This new approach addresses limitations in existing systems by mapping sentences to zero, one, or multiple image regions, accommodating multi-region findings and non-groundable phrases like negations. MedGrounder was trained in a two-stage process, first on sentence-anatomy box alignment and then fine-tuned on sentence-human annotated box datasets. Experiments on PadChest-GR and MS-CXR datasets demonstrate its strong zero-shot transfer capabilities and superior performance over existing baselines, particularly for complex phrases, while requiring fewer human annotations. AI

IMPACT Enhances interpretability of radiological reports by improving the mapping of text to image regions.

    Generalised Medical Phrase Grounding

    arXiv:2512.01085v3 Announce Type: replace-cross Abstract: Medical phrase grounding (MPG) maps textual descriptions of radiological findings to corresponding image regions. These grounded reports are easier to interpret, especially for non-experts. Existing MPG systems mostly foll…
