    • [PROBLEMS] In a radioactive diagnostic imaging agent comprising a radioactive halogen-labeled compound as an active ingredient, to prevent the radiation degradation of the active ingredient to increase the stability of the radioactive diagnostic imaging agent. [MEANS FOR SOLVING PROBLEMS] A biologically acceptable saccharide or sugar alcohol is added to the radioactive diagnostic imaging agent in an amount effective for the prevention of the radiation degradation. The amount of the saccharide or sugar alcohol to be added is preferably 10 (mmol/L)/GBq/mL or more, more preferably 50 (mmol/L)/GBq/mL or more. The saccharide is preferably selected from the group consisting of erythrose, threose, ribose, arabinose, xylose, lyxose, allose, altrose, glucose, mannose, gulose, idose, galactose, talose, erythrulose, ribulose, xylulose, psicose, fructose, sorbose and tagatose. The sugar alcohol is preferably selected from the group consisting of erythritol, xylitol, sorbitol and mannitol. ® KIPO & WIPO 2008
