NMR CONTRAST AGENTS
摘要:
An agent for modifying H2O relaxation times in NMR diagnosis comprises a polysaccharide having chemically linked to it an organic complexant to which is complexed a paramagnetic metal ion. Polysaccharides include cellulose, starch, sepharose and dextran. Organic complexants include EDTA, DTPA and aminoethyl diphosphonate. A preferred metal ion is Gadolinium (III). The agents can be administered orally or parenterally.
