This study presents the radiologic findings of 21 confirmed cases of COVID-19 infection in Shenzhen and Hong Kong, along with a literature review of other studies. The primary imaging pattern observed was ground-glass opacification, occasionally accompanied by consolidation in the periphery. Pleural effusions and lymphadenopathy were absent in all cases. Patients showed evolution from ground-glass opacities to consolidation and subsequent resolution. CT was found to be more sensitive than chest radiography in detecting these changes. The literature review confirmed bilateral and peripheral ground-glass opacities as the predominant findings in CT chest examinations. The study highlights the importance of CT in diagnosing and monitoring COVID-19, especially in asymptomatic patients, and suggests that chest radiography may lack sensitivity for certain manifestations of the infection. The findings are consistent with previous studies on SARS, indicating similarities in the radiologic profile of these coronavirus infections.This study presents the radiologic findings of 21 confirmed cases of COVID-19 infection in Shenzhen and Hong Kong, along with a literature review of other studies.
