Figure 8 High magnification (bar = 10 µm; magnification 1,420x) scanning electron microscopy pictures (left panels) and their respective low mechanical index pulse sequence scheme (PSS) images (right panels). Panel A demonstrates the presence of retained microbubbles in the endothelium detected by PSS in the left injured carotid artery, and Panel B reveals the absence of microbubbles in the endothelium in the control right side. Scanning electron microscopy revealed sites of injury with endothelial denudation and attachment of microbubbles (black arrows) to the denuded endothelium only in the injured vessel (A) and normal-appearing endothelium in the control vessel (B).
