New PAR dataset released for prostate biopsy AI analysis

By PulseAugur Editorial · [1 sources] ·

Researchers have released the PAR dataset, a collection of 1,017 whole slide images of prostate biopsy samples from 185 patients in Erbil, Iraq. This dataset aims to address the scarcity of histopathology data, particularly for underrepresented populations in the Middle East, to improve the generalizability of AI models in digital pathology. The images were scanned using Leica, Hamamatsu, and Grundium scanners and are associated with Gleason scores and International Society of Urological Pathology grades, enabling analyses of grading concordance, color normalization, and cross-scanner robustness.

    The PAR dataset: Prostate biopsy whole slide images from an underrepresented Middle Eastern population

    arXiv:2512.03854v2 Announce Type: replace Abstract: Artificial intelligence (AI) is increasingly used in digital pathology. Publicly available histopathology datasets remain scarce, and those that do exist predominantly represent Western populations. Consequently, the generalizab…
