Researchers have developed a new method for disease recognition from reactive central nervous system tissue, addressing the challenge of sampling errors in brain biopsies. They benchmarked four pathology foundation models—UNI2-h, Virchow2, Prov-GigaPath, and H-optimus-0—within a multiple-instance learning framework. The study found that while coarse disease prediction could be influenced by factors like slide size, finer diagnostic distinctions remained predictable above chance even after controlling for these confounds. Performance was statistically similar across all tested foundation models, indicating that current patch representations are not a limiting factor for recovering weak morphological signatures. The research also highlights the importance of auditing for acquisition shortcuts, such as blood introduced during tissue sampling, by using provenance-only baselines in computational pathology. AI
