GAstric GLands (GAGL) dataset. - v.1 GAGL 'minimal dataset' (a part of GAGL dataset) consists of 9 downsampled WSI including 3 normal, 3 gastric atrophic and 3 intestinal metaplasia cases. The minimal dataset could be used for the validation of the study findings of the following study: A digital pathology workflow for the segmentation and classification of gastric glands: Study of gastric atrophy and intestinal metaplasia cases. GAGL dataset consists of 85 WSI, collected from 20 patients. Gastric tissues were collected at University College London Hospital NHS trust, with ethical approval (research ethics committee (REC) reference: 15/YH/0311, & 19/LO/0089), with informed consent taken for prospective tissue collection. Samples were collected prospectively from patients undergoing gastrectomy for cancer, or sleeve gastrectomy for weight loss, with archival tissue used from endoscopic surveillance biopsies. Tissue underwent routine Hematoxylin & Eosin (H&E) staining. More specifically, the dataset includes 14 normal, 26 GA and 45 IM images. Please cite as: To be confirmed.

The IMGL (Intestinal Metaplasia gastric GLands) dataset includes 500 normal and 500 gastric glands with intestinal metaplasia. Gastric tissues were collected at University College London Hospital NHS trust, with ethical approval with informed consent taken for prospective tissue collection. The tissues underwent routine H&E staining. Please cite as: Barmpoutis P, Yuan J, Waddingham W, Ross C, Kayhanian H, Stathaki T, Alexander DC, Jansen M (2022).
