The present invention relates to stabilizedTc radiopharmaceutical compositions, which include both a radioprotectant and one or more antimicrobial preservative(s), and hence have an extended lifetime of use. The radioprotectant is ascorbic acid, para-aminobenzoic acid, gentisic acid or a salt thereof with a biocompatible cation, and the antimicrobial preservative is one or more compound from the paraben series of preservatives. The invention is particularly useful for cationic, lipophilicTc heart imaging agents such as Myoview&#x2122;.

Stabilized radiopharmaceutical compositions

A complex of a radiometal or paramagnetic metal ion with a metal chelating agent such as a diaminedioxime has attached thereto a substituent of formula (Y)-A-NHR)can function as a substrate for the fibrin-stabilizing Factor XIIIa. The complex is useful for the diagnosis or therapy of thrombosis, embolism, atherosclerosis, inflammation or cancer.

Labelled factor XIIIa substrates

A complex of a radiometal or paramagnetic metal ion with a metal chelating agent such as a diaminedioxime has attached thereto a substituent of formula &mdash;(Y) &mdash;A&mdash;NHR, can function as a substrate for the fibrin-stabilizing Factor XIIIa. The complex is useful for the diagnosis or therapy of thrombosis, embolism, atherosclerosis, inflammation or cancer.

A human leucocyte elastase (HLE) inhibitor labelled with a detector moiety where the inhibitor is synthetic and has a molecular weight of less than 2000, is useful for the diagnostic imaging of sites of inflammation of infection in vivo, for labelling leucocytes in vitro, or for radiotherapy of rthritis. The HLE inhibitor is preferably a &bgr;-lactam or an azetidinone.
