    摘要: A method of using .sup.99m technetium for tagging excipients in medical diagnosis by scintigraphy comprises mixing, in an aqueous solution of alkali-metal pertechnetate, an excipient and a reducing agent in the form of a complex, which complex is such that the association constant of the anion with reduced technetium is less than the association constant of the excipient with reduced technetium, thereby forming a radio-pharmaceutical substance which is a complex between the excipient and .sup.99m technetium.

    摘要: A method for preparing a pyrophosphate-tin composition labelled with 99.sup.m technetium for medical diagnosis by scintigraphy, especially bone scintigraphy. A pyrophosphate solution and a freshly prepared stannous chloride solution are mixed together and then neutralized to a pH within the range of 5 to 7, the mixture is eventually lyophilized in order to obtain a pyrophosphate-tin complex in powder form which is then mixed with a solution containing 99.sup.m Tc, the last-mentioned final step of the method being carried out at the moment of use. The complex has a pyrophosphate-tin molecular ratio of at least 30.
