(A) and (C) Coronal microPET images of U87MG tumor-bearing mice at 0.5, 1, and 2 h post injection of approximately 3.7 MBq (100 µCi) of ¹⁸F-FP-2.5D or ¹⁸F-FP-2.5F, respectively. (B) and (D) Coronal microPET images of U87MG tumor-bearing mice at 0.5, 1, and 2 h after co-injection of approximately 3.7 MBq (100 µCi) of ¹⁸F-FP-2.5D and ¹⁸F-FP-2.5F with 10 mg c(RGDyK) per kg mouse body weight, respectively. Red arrows indicate tumors.
