The dataset consists of two types of radiologist annotations for the localization of 10 pathologies: pixel-level segmentations and most-representative points. Annotations were drawn on images from the [CheXpert](https://stanfordmlgroup.github.io/competitions/chexpert/) validation and test sets. The dataset also consists of two separate sets of radiologist annotations: (1) ground-truth pixel-level segmentations on the validation and test sets, drawn by two board-certified radiologists, and (2) benchmark pixel-level segmentations and most-representative points on the test set, drawn by a separate group of three board-certified radiologists.\r\n\r\nThe validation and test sets consist of 234 chest X-rays from 200 patients and 668 chest X-rays from 500 patients, respectively. The 10 pathologies of interest are Atelectasis, Cardiomegaly, Consolidation, Edema, Enlarged Cardiomediastinum, Lung Lesion, Lung Opacity, Pleural Effusion, Pneumothorax, and Support Devices.\r\n\r\nFor more details, please see our paper, [_Benchmarking saliency methods for chest X-ray interpretation_](https://doi.org/10.1038/s42256-022-00536-x).","description_withheld":null,"homepage":"https://github.com/rajpurkarlab/cheXlocalize/","introduced_date":"2022-10-10","introduced_date_note":null,"introduced_by":null,"license":{"name":"MIT License","url":"https://github.com/rajpurkarlab/cheXlocalize/blob/master/LICENSE.md"},"modalities":[{"name":"Images","url":"/datasets/modality/images"},{"name":"Biomedical","url":"/datasets/modality/biomedical"},{"name":"Medical","url":"/datasets/modality/medical"}],"tasks":[{"name":"Semantic Segmentation","url":"/task/semantic-segmentation","datasets_with_task":"/datasets/task/semantic-segmentation"},{"name":"Medical Image Segmentation","url":"/task/medical-image-segmentation","datasets_with_task":"/datasets/task/medical-image-segmentation"},{"name":"2D Semantic Segmentation","url":"/task/2d-semantic-segmentation","datasets_with_task":"/datasets/task/2d-semantic-segmentation"},{"name":"Weakly-Supervised Semantic Segmentation","url":"/task/weakly-supervised-semantic-segmentation","datasets_with_task":"/datasets/task/weakly-supervised-semantic-segmentation"},{"name":"Weakly supervised Semantic Segmentation","url":"/task/weakly-supervised-semantic-segmentation-1","datasets_with_task":"/datasets/task/weakly-supervised-semantic-segmentation-1"},{"name":"Weakly-Supervised Object Segmentation","url":"/task/weakly-supervised-object-segmentation","datasets_with_task":"/datasets/task/weakly-supervised-object-segmentation"},{"name":"Medical X-Ray Image Segmentation","url":"/task/medical-x-ray-image-segmentation","datasets_with_task":"/datasets/task/medical-x-ray-image-segmentation"},{"name":"Weakly supervised segmentation","url":"/task/weakly-supervised-segmentation","datasets_with_task":"/datasets/task/weakly-supervised-segmentation"}],"languages":[{"name":"English","url":"/datasets/language/english"}],"variants":["CheXlocalize"],"data_loaders":[],"num_papers_in_archive":3,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[],"papers_with_a_benchmark_row":[],"syntology_totals":{"read_at":"2026-09-24T18:15:14+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
