Fig. 8.

Lung ultrasound images acquired using a linear-array probe. (a) Interrupted pleural line and patchy consolidation in the left posterior lower area, with fixed B-lines. The origin point is round and dull, and the subpleural area thickened. Color Doppler flow imaging shows no blood flow signal. (b) The pleural line in the right posterior upper area is interrupted and disappears. There is an air bronchogram sign in the strip and faint consolidation, and the connecting surface of the lung tissues is rough and unsmooth, with B-lines. (c) Discontinuous pleural line in the right posterior lower area and strip consolidation and air bronchogram sign, with a large number of B-lines. Reprinted with permission from Huang et al. (2020).
