CEUS renal perfusion images.

<p>CEUS renal perfusion images were converted into a time-intensity curve (TIC) by Q-LAB quantification software, which was generated from the region of interest (ROI). (a) TIC of dog’s right kidney before operation. (b) TIC of dog’s right kidney 5 weeks after the placement of AC. (c) TIC of dog’s right kidney 7 weeks after the placement of AC. TIC showed weekly delayed enhancement and perfusion in the renal perfusion curve. The slope rate of ascending curve was lower and descending curve was higher. It took more time to reach the peak intensity.
