| Research Abstract |
In this study, we prepared positron emitter ^<76>Br labeled Meta-bromobenzylguanidine (^<76>Br-MBBG), and investigated the utilities as a PET reagent. 76Br-MBBG was administrated to pheochromocytoma bearing mice, and displayed higher accumulation in tumor at 3 hours after administration. In PET imaging studies, 76Br-MBBG depicted pheochromocytoma clearly. These results strongly indicated that 76Br-MBBG is useful PET reagent for pheochromocytoma.
