Reviewing over the journals published every month from the world on topics in chest imaging, we may feel like more than 60 % of the articles are dealing with COVID-19 issue, the most pressing threat to human life and social activities in the world. As of the beginning of December 2020, EJR Open has already published 8 articles on COVID-19 pneumonia and one article in mammography for the second wave of COVID-19. However, it is probably also important to continue to work on diverse research activities broadly including topics outside of COVID-19. One thing seems to be clear to all of us is the fact that the year 2020 will be remembered in history as an epoch-making year, when the human life has drastically and irreversibly changed, even with postponing the Olympic Games since 1916 (Berlin), 1940 (Tokyo/Helsinki), and 1944 (London).
In this Special Issue for Chest Imaging 2021, 4 review articles and 7 original articles have been contributed. Dr. Yoo and Professor Kyung Soo Lee at Samsung Medical Center and Sungkyunkwan University contributed the review article on Connective Tissue Disease Related Lung Disease (CTL-ILD), very hot and evolving topic in pulmonary medicine [
