摘要:
The invention relates to conjugates that consist of macrocyclic metal complexes with biomolecules and their production. The conjugates are suitable as contrast media in NMR diagnosis and radiodiagnosis as well as as agents for radiotherapy. High relaxivity is achieved by a special liganding of macrocyclic compounds, and a fine-tuning of the relaxivity is made possible.
