Abstract
Ibandronate was successfully labeled by using technetium-99m with maximum radiochemical yield (98.6%). The process is achieved by adding (25 µg) from stannous chloride in addition to (300 µg) of Ibandronate at room temperature in pH=7 for 15 min., we obtain a radiochemical yield (98.6%) and the radiolabeled complex was purified by high performance liquid chromatography (HPLC). The radiochemical yield was affected by many factors such as: Ibandronate amount, stannous chloride amount, reaction time, temperature of the reaction and pH of the reaction mixture. The in-vitro stability of 99mTc-Ibandronate was determined along (8 hours). The data obtained approve that 99mTc-Ibandronate complex was stable along (6 hours) without detection of any by-products in the reaction mixture.Biodistribution study showed high uptake and long retention of 99mTc-Ibandronate in bone was (44.32 % ID/organ) at (1 hour) post injection. Thus, 99mTc–Ibandronate could be used as a selective potential imaging agent for diagnosis of bone diseases
