ABSTRACT:
An NMR contrast agent composition contains a complex of a selected metal ion and a selected ligand. The ion is selected from the group consisting of gadolinium (III), iron (III), manganese (II), manganese (III), chromium (III), copper (II), dysprosium (III), terbium (III), holmium (III), erbium (III), europium (II), and europium (III); and the ligand is a linear two-nitrogen compound having one 2-hydroxy-aryl group at one of the nitrogens; or the ligand is a linear two-nitrogen compound having one or two 2-hydroxy-aryl groups at each of the nitrogens; or the ligand is a linear three-, four-, or five-nitrogen compound having one or two 2-hydroxy-aryl substituents at each of one or more of the nitrogens, or the ligand is a heterocyclic compound having a ring containing three or four nitrogens, and having a 2-hydroxy-aryl substitent at one or more of the nitrogens; or the ligand is a heterocyclic compound having a ring containing 4 nitrogens, and having a carboxyl group at two of the nitrogens and an aromatic substituent at the other two of the nitrogens.
