Differences in Clinical and Imaging Features between Asymptomatic and Symptomatic COVID-19 Patients

Figure 2

The imaging features of asymptomatic carriers (Asy) and symptomatic COVID-19 patients. (a) The pulmonary lobes that are involved at different stages of the two populations (asymptomatic carriers vs. COVID-19 patients). (b) The density of lesions in the lungs, as well as interstitial changes in the lungs of the two populations (asymptomatic carriers vs. COVID-19 patients). (c) The distribution of lesions of the two populations (asymptomatic carriers vs. COVID-19 patients). (d) The duration from progression and improvement stages to disease onset of the two populations (asymptomatic carriers vs. COVID-19 patients). GGO, ground-glass opacity; CON, consolidation.
