Ex vivo quantification and validation of 18F-FDG retention in angioplasty-induced injury of the femoral artery. A Representative example of excised peripheral arteries harvested at 2 weeks after balloon-induced injury for gamma counting and anatomically matched histological analyses (arrows denote region of injury). B Post-mortem gamma counting of excised arterial segments from injured and control femoral arteries demonstrated significantly higher 18F-FDG uptake in injured arteries 2 weeks after balloon angioplasty. C Pearson’s correlation demonstrated a significant association between quantitative analysis of 18F-FDG uptake from in vivo PET/CT imaging and ex vivo gamma counting, n = 7 animals. Data are shown as means ± SEM
