Lung ultrasound (LUS) features and corresponding chest computed tomography (CT) findings in patients with COVID-19

LUS	Chest CT
Thickened pleural line	Thickened pleura
B-lines (multifocal, discrete or confluent)	Ground-glass shadowing
Confluent B-lines	Pulmonary infiltrating shadowing
Small consolidations	Subpleural consolidation
Both non-translobar and translobar consolidation	Translobar consolidation
Pleural effusion rare	Pleural effusion rare
Multilobar distribution of abnormalities	More than two lobes affected
Early stages: Focal B-lines and pleural-line thickening	Early stages: Negative or atypical findings
Progressive and late stages: Confluent B-lines, pleural-line thickening, then small consolidation which progress to lobar consolidation	Progressive and late stages: Diffuse scattered or ground-glass shadow which progresses to lung consolidation
