This article highlights an incredibly exciting Multimodal challenge from MICCAI 2025 that pushes the boundaries of Computer Vision and Large Language Models (LLMs) in healthcare. By automatically generating structured pathology reports from massive giga-pixel Whole Slide Images (WSIs), this technology has the potential to drastically reduce diagnostic workloads and assist medical professionals. The integration of diverse global datasets across seven organs showcases a massive leap forward in medical AI scalability and practical application.
Key Takeaways
- •The REG2025 challenge tasks AI with generating structured pathology reports from giga-pixel images across 7 different organs using a massive dataset of 10,500 cases from 6 global facilities.
- •Scoring heavily emphasizes medical accuracy, with the matching rate of precise medical keywords (KEY score) accounting for 40% of the final evaluation.
- •Successful approaches require a brilliant combination of three skills: extracting features via pathology Foundation Models, aggregating data using Multiple Instance Learning, and generating text with an LLM.

It is like being asked to write a 'characteristics report of this city' from an aerial photograph of the 23 wards of Tokyo; since it is impossible to see the whole picture at once, it must be divided into small blocks for processing, and then summarized at the end."
