CXR-PRO: MIMIC-CXR with Prior References Omitted

CXR-PRO is an adaptation of the MIMIC-CXR dataset that omits references to prior radiology reports. Consisting of 374,139 free-text radiology reports and associated chest radiographs, CXR-PRO addresses the issue of hallucinated references to priors produced by radiology report generation models. By removing nearly all prior references in MIMIC-CXR, CXR-PRO, when used as training data for report generation models, is capable of broadly improving the factual consistency and accuracy of generated reports. More generally, this dataset aims to support a wide body of research in medical image analysis and natural language processing. MIMIC-CXR is a de-identified dataset, so no protected health information (PHI) is included.
