  • Water-soluble, carrier-bound paramagnetic metal containing diagnostic agents
    Patent number: 4986980
    Abstract: 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.
    Type: Grant
    Filed: November 1, 1985
    Date of Patent: January 22, 1991
    Assignee: Nycomed AS
    Inventor: Trond Jacobsen
  • A diagnostic agent containing a non-radioactive paramagnetic metal species in a macromolecular carrier
    Patent number: 4985233
    Abstract: A paramagnetic metal species-containing diagnostic agent is disclosed which comprises a non-radioactive paramagnetic metal species and, as a carrier therefor, a physiologically tolerable, water-insoluble, hydroxyl group-containing, particulate macromolecular product consisting essentially of at least one polymeric or polymerized carbohydrate or polymerized sugar alcohol or derivative thereof.
    Type: Grant

    Inventors: Jo Klaveness, Trond Jacobsen, Bernt J. Lindberg
  • Method of NMK imaging using a contrast agent comprising particles of a ferromagnetic material
    Patent number: 4863715
    Abstract: Ferromagnetic particles, conveniently embedded in or coated by a biotolerable polymer and held in dispersion in a physiologically acceptable dispersion medium, may be used as contrast agents in nmr imaging for the production of images suitable for use in diagnosis. Unlike paramagnetic nmr contrast agents, ferromagnetic nmr contrast agents give particularly good contrast in the T.sub.2 dependent images.
