Figure 2D. Regional perfusion curves, example of one animal.

Figure 2D

The regional perfusion curves show that the microvascular perfusion decreased the most in the outer medulla during the first hour post-IR and its recovery took longer time compared to the cortex or to the inner medulla. Blue=cortex, Green=outer medulla, Red=inner medulla. Regions of interest selection on parametric maps and on B-mode images are shown in the lower panel of the figure. The region of interest selection was performed on the parametric perfusion maps (left panel) and confirmed on B-mode and contrast images at pre-IR, 15 min post-IR and 24 hr post-IR. The selected regions were maintained (placed automatically) on consecutive images (15-, 30-, 45-, and 60 min post-IR). The right panel shows an overlay of the region selectioned onto a photograph of the freshly excised parasagittal view of the mouse kidney.
