DIAGNOSTIC AGENT CONTAINING A NON-RADIOACTIVE metal species chemically bonded to the macromolecular RELATIONS AND USE OF THESE RELATIONS WITH CONVENTIONAL metal species FOR PRODUCTION OF A MEANS TO BE USED FOR NMR AND ULTRASONIC

摘要

There is disclosed a diagnostic agent containing a non-radioactive paramagnetic metal species which agent comprises a physiologically tolerable, water-soluble, hydroxyl group-containing macromolecular product to which is chemically bound said metal species, said product consisting essentially of at least one polymeric or polymerized carbohydrate or polymerized sugar alcohol or derivative thereof.
