Fibrotic-like changes after critical COVID-19 in a patient in his early 70s. (A) Posteroanterior chest radiograph obtained 7 months after infection shows reticular opacities with a slight peripheral predominance diffusely distributed in both lungs. (B) Image from the same radiograph analysed by the artificial intelligence algorithm with a heat map highlighting the areas of pulmonary involvement. (C, D) Chest CT obtained 8 months after infection shows moderate ground glass opacities, linear multifocal and reticular abnormalities, discrete traction bronchiectasis and slight parenchymal architectural distortion. The patient had dyspnoea (modified Medical Research Council dyspnoea scale=1) and altered forced vital capacity (2.34 L/60% pred), besides the normal oximetry (97%).
