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 follow the referring expression comprehension (REC) paradigm and return exactly one bounding box per phrase. Real reports often violate this assumption. They contain multi-region findings, non-diagnostic text, and non-groundable phrases, such as negations or descriptions of normal anatomy. Motivated by this, we reformulate

Why this matters
Why now

The continuous advancements in AI and natural language processing are enabling more sophisticated applications in specialized domains like medical imaging.

Why it’s important

Improved medical phrase grounding enhances the interpretability of radiological reports, potentially leading to more accurate diagnoses and better patient outcomes.

What changes

This research moves beyond simplistic one-to-one mapping in medical imaging AI, embracing the complexity of real-world clinical documentation which includes multi-region findings and non-diagnostic text.
