A small subset of studies has been annotated with binary pixel masks depicting regions of interests (ground-glass opacifications and consolidations). CT scans were obtained between 1st of March, 2020 and 25th of April, 2020, and provided by municipal hospitals in Moscow, Russia.\r\n\r\nSource: [MosMedData: Chest CT Scans With COVID-19 Related Findings Dataset](/paper/mosmeddata-chest-ct-scans-with-covid-19)","description_withheld":null,"homepage":"https://mosmed.ai/en/","introduced_date":null,"introduced_date_note":null,"introduced_by":{"paper":"/paper/mosmeddata-chest-ct-scans-with-covid-19","title":"MosMedData: Chest CT Scans With COVID-19 Related Findings Dataset","first_author":"S.
