French ‘Société Française de Radiologie’ and ‘Société Française d’Imagerie Thoracique’ adapted classifications for the radiological findings in the setting of a suspicion of coronavirus disease 2019 (COVID-19), or SFR-SIT diagnostic score, categorised as the following: a I: no pathologic findings; b II: non-SARS-CoV-2 infections (herein, bacterial bronchopneumonitis, black arrowheads); c III: indeterminate (herein, subtle subpleural condensations, white arrowhead); d IV: pathologic findings compatible with COVID-19 (herein, a unique subpleural area of ground glass opacity, white arrowhead); e V: pathologic findings typical for COVID-19 lung disease (i.e. multiple ground glass opacities seen in ≥ 2 lobes, with a subpleural predominant locations, possibly associated with band-like condensations and reversible fibrosis). All CT images are in axial plane and lung kernel
