Abstract
Complexes of bicyclopolyazamacrocyclocarboxylic acid with Gd, Mn or Fe ions are disclosed. The complexes can be covalently attached to a biologically active molecule, e.g. an antibody or antibody fragment, to form conjugates. The complexes and conjugates are useful as contrast agents for diagnostic purposes.
