Imaging related to underlying immunological and pathological processes in COVID-19

Figure 14  Lung ultrasound image. A: Lung ultrasound image obtained with convex probe shows multiple B-lines (arrow) and subpleural consolidations seen as hypoechoic regions (asterix) that appear tissue-like with an irregular deep border (shredded fractal line) abutting the more aerated lung, which has echogenic artefacts (arrowhead); B: Lung ultrasound image obtained with convex probe. Multiple linear vertical artefacts - B-lines (arrows), and thickened pleural line (between arrowheads) are visualized; C: Lung ultrasound image obtained with convex probe. Multiple confluent B-lines are seen (white lung).
