Abstract
A method for producing a radioactive diagnostic imaging agent containing a radioactivefluorine-labeled organic compound represented by the following formula (1): as an effective ingredient in which radiolysis of the effective ingredient is inhibited, involves providing a solution containing the radioactivefluorine-labeled organic compound represented by the above formula (1), adding an acid to the solution obtained in the first step in an amount sufficient for the solution to be kept within a pH of 2.0-5.9 in the following third step, and diluting the solution obtained in the second step in order to adjust the solution to a desired radioactive concentration within a pH of 2.0-5.9.
