The Research and Practical Center of Medical Radiology in Moscow has published a dataset of chest CT studies for use in training machine-learning algorithms.
The dataset contains 500 anonymized chest CT studies with mapped lesions. Each image was tagged by three radiologists and subsequently verified by an expert. The long-term project resulted in a structured database and an official authorship certificate.
The MoscowRadiology-CTLungCa-500 dataset is available for free for developers of medical artificial intelligence algorithms and other parties.
