Abstract
Stable injection solutions of radiodiagnostic aids ready for use are obtained by addition to the organ-or tissue-specific carrier, before, during or after the labeling with the pertechnetate, of a compound of the formula: ##STR1## in which R denotes hydrogen, and R' denotes a sulpho- or a carboxymethyl group, or R and R' each denote a sulpho- or a carboxymethyl group, or a water-soluble salt thereof, as stabilizer. These compounds do not alter the specific organ or tissue distribution of the carrier.
