Results of blocking experiments performed in five xenograft mice: a with SUVmean values obtained at the 2nd hour of PET recording for tumors and various organs, after the injection of 68Ga-NODAGA-RGD (black hatched bar), as compared with the co-injection of 68Ga-NODAGA-RGD with excess unlabeled RGD (gray bars) and b with examples of superimposed Maximal Intensity Pixel images obtained in the same animal with 68Ga-NODAGA-RGD alone (left image of mice) and with 68Ga-NODAGA-RGD co-injected with unlabeled RGD (right image of mice). The two tumors are indicated with white arrows and the color scale is expressed in SUV values. *p < 0.05 for paired comparisons
