Figure 4
Whole-body coronal microPET image of an athymic male nude mice bearing LNCaP tumor xenograft. The monomer [68Ga]6 (A) and the dimer [68Ga]7 (B) were evaluated by a dynamic microPET scan followed by a static scan. The static scans 1 h post-injection of [68Ga]6 and [68Ga]7 are shown in (A) and (B), respectively. Approximately 15 MBq/mouse was injected. (C) The graph shows the respective time-activity curves in the muscle and tumor for both tracers. (D) The graph demonstrates the elimination of [68Ga]7 from other organs in PET.
