摘要
Tri- and tetra-cyclopolyazamacrocyclophosphonic acid compounds and their derivatives are disclosed which may form inert complexes with Gd, Mn or Fe ions. The overall charge of the complex can be varied to alter the in vivo biolocalization. The complexes are useful as contrast agents for diagnostic purposes.
