Zusammenfassung:	Aqueous solutions of 99technetium salts wherein the 99technetium is in reduced valencey state, when administered to mammals, permit identification of the skeleton and of calcareous tumors by scintigraphy (radiographic scanning). The solutions are conveniently prepared by mixing one ore more phosphonic acids (or their salts) with one or more reducing salts, and adding the mixture to an aqueous solution of a pharmaceutically acceptable 99pertechnetate salt. Reduction of the valence of the technetium occurs rapidly, and the resulting solution is adequately stable for use in scintigraphy.
