Representative sequential computed tomography (CT) scans of a 56-year-old male coronavirus disease 2019 (COVID-19) patient during acute disease and follow-up. Pulmonary three-dimensional modelling assessed with CT is shown a) during acute COVID-19, b) at 60 days follow-up and c) at 100 days follow-up. Pulmonary opacities, mainly reflecting ground-glass opacities and/or consolidation, were quantified with Syngo.via CT Pneumonia Analysis software (Siemens Healthineers, Erlangen, Germany). Areas with increased opacity are marked in red, whereas normal lung areas are indicated in green.
