Abstract Objective: To study the CT findings and dynamic imaging changes of COVID-19. Methods: A total of 60 patients with COVID-19 from the Third Affiliated Hospital of Wenzhou Medical University from January 26, 2020 to March 15, 2020 were included. All patients underwent sequential CT examinations with an interval of 2-10 days. The CT features in the initial, progressive and dissipating stage were analyzed. Results: In the initial stage, 21 cases had small ground-glass opacities accounting for 75.0% and, 7 cases nodules accounting for 25.0%. In progressive stage, ground-glass opacities accompanied by consolidations were found in 49 cases (81.7%), prominent consolidations in 11 cases (18.3%). Multiple lesions were found in 52 cases (86.7%), 44 cases (73.3%) were found lesions in the middle and lower lobes of both lungs, and 55 case (91.7%) were mainly located under pleura. In dissipation stage, the number of lesions decreased in 49 cases (81.7%), the range decreased in 60 cases (100%) and the density decreased in 60 cases (100%). Ground-glass change were observed again in 36 cases (60.0%) and 24 cases (40.0%) had strip solid change. After absorption, 9 cases (15.0%) had residual subpleural arc shadow and interlobular septal thickening. Conclusion: CT is able to distinctly demonstrate the distribution, density, shape, and range of pulmonary lesions of COVID-19, and display pulmonary fibrosis as well. Therefore, CT can be used to display the early abnormalities and dynamic changes of COVID-19.

Key words： coronavirus disease 2019 tomography, X-ray computed dynamic changes
