B-mode chest ultrasound. A: Representation with markings corresponding to the A, B, and pleural lines. The B-line (asterisks) represents vertical, hyperechogenic artifacts that cover the entire anteroposterior field analyzed. An important characteristic is that they eliminate the A-lines (yellow arrow) when crossing (X). The pleural line is shown as a hyperechogenic line (red arrow). B: Image demonstrates B-mode chest ultrasound without indicative markings.
