Figure 3. US imaging of PLM and Sonovue in the rabbit iliac arteries.
(A) The rabbits were administrated with PLM (Top two rows) or Sonovue (bottom two rows) at the same bubble concentrations. After bubble perfusion, US images were obtained at 0.1 s, 0.5 s, 1 s, 3 s or 10 s. (B,C) The quantitative analysis of US signal intensities of selected regions after PLM or Sonovue perfusion at different times. The arrows are for the regions of iliac artery restenosis. Red boxes are for selected regions of the rabbit iliac arteries. White boxes for selected regions of tissue background. *P < 0.01.
