ABSTRACT:
A composition for preparing cationic lipophilic technetium complexes is described. The composition comprises an admixture of (a) an accelerator compound selected from the group of water-soluble organic bidentate ligands that are capable of coordinating with technetium to form a 4 to 6 member ring and (b) a target-seeking ligand, or aqueous salt thereof, having the structure indicated in formulas I, II or III. The accelerator compound has a weaker coordinating bond with technetium than the target-seeking ligand has with technetium.
