The CEUS image and the TIC image after IRI. a The CEUS image and the TIC image of the sham group 1 h after IRI. The green, yellow, and purple annular parts were three randomly selected sites in the renal cortex in the image, labeled as ROI 1, ROI 2, and ROI 3. The blue annular part was the location of the kidney in the image, labeled as ROI 4. PE values 1 h (b) and 24 h (c) after IRI. WiPI values 1 h (d) and 24 h (e) after IRI. The value for each mouse was calculated as the mean of the values of ROI 1, ROI 2, and ROI 3. Ns No significance, p > 0.05; *, p < 0.05; **, p < 0.01; ***, p < 0.001. a.u.
