Absolute value of glucose uptake in the region of interest of each hemisphere for the 18F-fluorodeoxyglucose positron emission tomography scans. Comparisons were made among the unilateral common carotid artery occlusion-operated mice with and without asymmetric uptake, and sham-operated mice. (A) The quantity of glucose uptake in the ipsilateral hemisphere was greater in the asymmetric group than in the other groups. (B) The quantity of glucose uptake in the contralateral hemisphere did not decrease in the asymmetric group, relative to other groups. (C) Finally, the uptake ratio of the right to left hemisphere was higher in the asymmetric group than in the other groups. * p<0.001.
