Abstract
Methods for the preparation and analysis of a new renal radiopharmaceutical,99mTc-thiodiglycolic acid (TDGA), are reported. The kit for Tc-TDGA contains a lypophilized acidic (pH 2.5) mixture of 5 mg TDGA and 0.05 mg SnCl2·2H2O. Acetate buffer has been found to be a suitable solvent for paper chromatography of99mTc-TDGA. The results of the quantitative organ distribution studies in rats and rabbits indicated the characteristics of99mTc-TDGA to be intermediate to the renal tubular agent131I-Hippuran and the GFR agent99mTc-DTPA.
