The radiology scientific literature is an important medium for the rapid dissemination of emerging information critical to the practice of radiology. We aimed to review the radiology literature response to the Covid-19 pandemic, including an analysis of the timing, sources and types of publications in the many radiology journals.

Materials and Methods:
A Pubmed search was performed of the radiology literature (defined as all journals in the Journal Citation Reports "Radiology, Nuclear Medicine, & Medical Imaging" category) to identify publications mentioning COVID-19, SARS-CoV-2, 2019-nCoV or novel coronavirus. Publications that were not relevant to radiology practice, non-English language publications, letters to the editor without original data or cases, letter responses, and errata were excluded. All publications were reviewed and data were recorded as to date of online publication, type of publication (i.e. case report, review, original research, etc.), country of origin, and other specifics regarding the content.

226 publications (from 34 journals) met inclusion criteria. During the study period, the number of new publications continually increased over time and the primary origin of publications shifted from China with 23 publications (79.3%) in weeks 1-4, and 50 publications (71.4%) in weeks 5-8, to a near-even mix in weeks 9-12 of China (30, 23.6%), Europe (35, 27.6%), the US (28, 22.0%), and Other or multiple countries (34, 26.8%). Overall, 103 (45.6%) were from China, 40 (17.7%) from Europe, 38 (16.8%) from the US, and 45 (19.9%) from Other or multiple countries. 176 (77.9%) were published in general imaging journals, and 50 (22.1%) in modality-specific or subspecialty journals (including nuclear medicine). Radiology had the most publications (41), followed by American Journal of Roentgenology (23), Academic Radiology (18), and European Radiology (18). Publications were comprised of 59 (26.1%) observational studies, 44 (19.5%) case reports/small case series (up to 6 patients), and 123 (54.4%) reviews, editorials, etc., including 19 society and expert panel statements.

The radiology literature responded quickly to address the COVID-19 crisis, with the rate of new publications increasing over time as greater numbers of publications originated from countries outside of China. Publications were predominantly in general radiology journals; these journals are an excellent resource for radiologists to keep informed of critical new knowledge pertaining to emerging pathology of import to the radiology community.
