In this study, we collected 100 cases of laboratory-confirmed COVID-19 pneumonia patients, including 84 cases with CT follow-up scan, to describe the CT imaging features and evolution of this disease. We investigated the CT imaging features of COVID-19 pneumonia and CT changes according to the disease course of a large sample of 100 patients with 272 CT scans in this study. In conclusion, the main CT signs of COVID-19 pneumonia mainly included GGO, GGO plus consolidation, and GGO plus reticular pattern, single or multiple focus onset, distributed predominantly in the peripheral, middle, and lower zones, and the posterior zone in bilateral lungs.	./cache/cord-333083-8bxqsga2.txt	./txt/cord-333083-8bxqsga2.txt
