MosMedData: chest XR with and without pulmonary nodules type VII

About Dataset

This dataset contains the results of chest XR with and without (normal) pulmonary nodules .
The research data were collected in the radiology departments of the Moscow medical
facilities between 16.11.2017 and 06.04.2022.
Two radiologists reviewed the studies and verified the presence of pulmonary nodules.
(The Fleischner Society glossary defines "pulmonary nodule" as a tumor of 6 to 30 mm in size, located in the lung parenchyma).
To make the dataset more balanced, we added chest CT studies w/o pathological findings.
An expert (a radiologist with more than 10 years of experience) did a final review of the dataset and verified the studies based on the CT results (within 2 weeks after RG).
The final dataset contains 100 studies: 50 w/ pathological changes (i.e., lung nodules); the other 50 w/o pathological changes.
