摘要:
The invention relates to new metal complexes of dendrimeric macromolecules that contain 8 to 64 ions of an element of atomic numbers 21-129, 39, 42-44, or 57-83 and a polymeric, complexing ligand of formula I A--(X).sub.b (I) in which A, X and b have different meanings, agents that contain these compounds as well as the use of the latter in diagnosis. The invention further relates to a process for the production of the complexes and agents.
摘要:
The invention relates to new, monomeric, perfluoroalkyl-substituted metal complexes, processes for their production, and their use in diagnosis and therapy.The compounds according to the invention are suitable especially as in vivo contrast media in nuclear spin tomography (MRT). They can preferably be used as blood-pool agents and as lymphographic agents.
