A, Schematic presentation of the experimental design. B, Representative fused microSPECT and CT angiography images of mice two weeks after left common carotid artery wire injury demonstrating focal uptake of RP805 in injured arteries. Arrows point to left (L) and right (R) carotid arteries, cpv: counts per voxel. C–D, In vivo quantification of RP805 uptake in carotid arteries demonstrating a significant reduction in left carotid background-corrected RP805 uptake at 2 and 4 weeks after injury in the withdrawal group. * P <0.05, ** P <0.001.
