This study was to investigate the preparation and biodistribution of (99m)Tc-labeled novel zoledronic acid derivative 1-hydroxy-2-(2-isopropyl-1H-imidazole-1-yl) ethylidene-1,1-bisphosphonic ((99m)Tc-i-PIDP) as a potential bone imaging agent. Satisfactory labeling results (radiochemical purity over 95%) were obtained when the amount of i-PIDP, Na(99m)TcO(4), and SnCl(2)·2H(2)O, were 5 mg, 37 MBq, and 100 μg, respectively, the pH value was between 4.0 and 6.0, and the labeling reaction continued for 30 min...
