Examples of conditions with B-lines. a Pneumonia with several LUS features: B-lines (asterisk) of uneven spacing, a small consolidation (arrow), and small effusion (dotted arrow). b Cardiogenic pulmonary edema with many evenly spaced B-lines (asterisk) banded together into a thick sheet. Note the smooth and thin pleural line (thin arrow). c ARDS with dense B-lines involving two intercostal spaces (1, 2). Note that an area in 1 (arrow) is spared, indicating the patchy distribution of the disease process. The pleura is thickened and uneven (dotted arrow)
