Patient selection included patients at least 18 years of age receiving a negative diagnosis\nfor COVID-19. The dataset includes 120 de-identified thoracic CT scans from COVID negative\npatients, along with supporting clinical variables including age, sex, exam description, image\ncount, modality, symptomatic status, testing result, and specimen source. The dataset was created\nthrough a collaboration between the RSNA and the Society of Thoracic Radiology (STR) to support\nmachine learning research and education for COVID-19 chest imaging. Data will be made available\nthrough the Medical Imaging Data Resource Center (MIDRC), funded through a contract with the\nNational Institute for Biomedical Imaging and Bioengineering (NIBIB).\nPlease see the MIDRC-RICORD-1B (https://doi.org/10.7937/31v8-4a40) page to learn more about\nthe images and to obtain any supporting metadata for this collection.","patients":117,"studies":120,"series":120,"instances":21220,"size_TB":0.009,"modalities":["CT"],"licenses":[{"license_short_name":"CC BY-NC 4.0","series":120,"size_TB":0.009}]}
