[48V]vanadyl-pheophorbide (48V-Pheo) was synthesized by insertion of 48V into pheophorbide (Pheo), a decomposition product from chlorophyll. At 24 h after injection, 48V-Pheo showed a clearer image of an FM3A tumor than inorganic 48V. This agent also accumulated in MH 134 and S 180 tumors as well as in FM3A tumors. The imaging efficiency was dependent on the affinity of Pheo for tumors.48V-Pheo seems to be suitable as a tumor imaging agent in conjunction with photodynamic therapy.
