Available data on COVID-19
Reference resources
This section lists the main international reference resources for imaging data. Part of these resources are ELIXIR Core Data Resources, a selection of European resources of fundamental importance for the life science community and for the long-term preservation of biological data.
The European Institute for Biomedical Imaging Research (EIBIR) is an organization dedicated to the coordination of research projects and aims to support the development of biomedical imaging technologies and the dissemination of knowledge. EIBIR is a non-profit research organisation founded by the European Society of Radiology. At the EIBIR website a dedicated page provides a summary of curated COVID-19 imaging datasets for teaching, training and research.
The BioImage Archive is a resource hosted at the EMBL-EBI aimed at facilitating the access to scientific image datasets linked to a publication or public studies from basic, preclinical and clinical research.
Electron Microscopy Public Image Archive (EMPIAR) is a database for raw, 2D electron microscopy images and tomography data.
The NIH in the US has launched the National COVID Cohort Collaborative (N3C) program to gather and analyze COVID-19 related clinical data, currently not including imaging. Considering the urgent need to have COVID-19 image data for all disease stages freely available for the research community, the NCI Cancer Imaging Program (CIP) is utilizing its Cancer Imaging Archive (TCIA) as a resource for making image sets public since it is uniquely ready to carry out a short term effort COVID-19 patient images for immediate reference by the community.
COVID-19 Datasets on TCIA:
CT Images in COVID-19 An image dataset consisting of chest Computed Tomographies (CT) from 632 patients with COVID-19 infections.
Chest Imaging with Clinical and Genomic Correlates Representing a Rural COVID-19 Positive Population A collection of radiographic and CT imaging studies for patients positive for COVID-19. Each patient is described by a limited set of clinical data correlates that includes demographics, comorbidities, selected lab data and key radiology findings. These data are cross-linked to SARS-COV-2 cDNA sequence data extracted from clinical isolates from the same population, uploaded to the Genbank repository.
Medical Imaging Data Resource Center - RSNA International COVID Radiology Database Release 1a - Chest CT Covid+ (MIDRC-RICORD dataset 1a) The Radiological Society of North America (RSNA) assembled the RSNA International COVID-19 Open Radiology Database (RICORD), a collection of COVID-related imaging datasets and expert annotations to support research and education called MIDRC-RICORD dataset 1a consisting of 120 thoracic CT scans from four international sites annotated with detailed segmentation and diagnostic labels.
The Radiological Society of North America (RSNA) provides a dedicated page to COVID-19 pandemic with imaging guidelines, tools and images for research and educational purpose. Access to a forum for the COVID-19 imaging community is also available upon registration.
Resources at the European COVID-19 Data Portal
- The European COVID-19 Data Portal is a resource developed at the European Bioinformatics Institute (EMBL-EBI) and proposes a collection of data related to SARS-CoV-2 with a page dedicated to imaging data.
Resources developed in Italy
The Italian Society of Medical and interventional Radiology (SIRM) provides a curated database of selected Covid-19 cases with RX and TC imaging data collected at italian hospitals (N=68 as Nov. 24, 2020). The site provides a structured report (https://www.sirm.org/en/2020/03/31/covid-19-structured-report/) for the providers of data related to thoracic CT imaging of Covid-19 cases
The axial CT images available at the SIRM database (see above) were segmented by a radiologist for the MEDSEG project for the manual or AI aided CT images segmentation. Dataset of 100 axial CT images from >40 patients using 3 labels: ground glass, consolidation and pleural effusion.
