TL;DR
This paper introduces a publicly available dataset of 339 prostate biopsy whole-slide images from Iraqi patients, aiming to enhance AI model generalizability across diverse populations in digital pathology.
Contribution
It provides the first comprehensive Middle Eastern prostate biopsy dataset with associated pathology annotations for AI research and validation.
Findings
Dataset includes images from multiple scanners.
Slides are annotated with Gleason scores and ISUP grades.
Supports development of robust, generalizable AI models.
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 generalizability of AI models to populations from less digitized regions, such as the Middle East, is largely unknown. This motivates the public release of our dataset to support the development and validation of pathology AI models across globally diverse populations. We present 339 whole-slide images of prostate core needle biopsies from a consecutive series of 185 patients collected in Erbil, Iraq. The slides are associated with Gleason scores and International Society of Urological Pathology grades assigned independently by three pathologists. Scanning was performed using two high-throughput scanners (Leica and Hamamatsu) and one compact scanner (Grundium). All slides…
