Figure 9 Pneumothorax. A: B-mode image (right image) shows horizontal reverberation artefacts corresponding to frozen echoes in M-mode image (left image), due to loss of breathing-dependent motion of pleural line; B: After resolution of pneumothorax, B-mode image (right image) shows pleural line and a single comet-tail artefact; in M-mode image (left image), breathing-dependent movements appear as “frosted glass” artefacts, quite different from frozen echoes seen in A.
