  • Contrast agents for magnetic resonance imaging aminosaccharide
    Patent number: 5804163
    Abstract: A contrast enhancing agent for magnetic resonance images having a chelating agent, which can be bound to metals having at least one unpaired electron. Examples of such chelating agents include 3,6,9-tris(carboxymethyl)-1, 11-bis(dimethylamine)-3,6,9-triazaundecane; 3,6,9-tris(carboxymethyl)-1, 11-bis(diethanolamino) 3,6,9-triazaundecane; 3,6,9-tris(carboxymethyl)-1, 11-bis(tris(hydroymethyl) aminomethane)-3,6,9-triazaundecane; 3,6-bis(carboxymethyl-1,8-bis(N-carboxymethylglucosamino)-3,6-diazoctane; DTPA-bis(galactosamide), DTPA-Bis(glucosamide), DTPA-Bis(pyridoxamide), and poly-(DTPA-ethylenediamide).
    Type: Grant
    Filed: July 14, 1994
    Date of Patent: September 8, 1998
    Assignee: Magnetic Research, Inc.
    Inventors: Wendell A. Gibby, N. Rao Puttagunta
  • Polymeric contrast enhancing agents for magnetic resonance images
    Patent number: 5466439
    Abstract: A polymeric contrast enhancing agent for magnetic resonance images having a chelating agent, which can be bound to metal ions having at least one unpaired electron, such as gadolinium. Examples of such chelating agents include DTPA-ethylenediamide-methacrylate copolymer and poly-(DTPA-ethylenediamide). These contrast enhancing agents, bound to the metal ions, are then administered to a patient, and following this the MR images are taken.

  • Contrast enhancing agents for magnetic resonance images
    Patent number: 4933441
    Abstract: A nonionic contrast enhancing agent for magnetic resonance. In a preferred embodiment a chelating agent, for example, EDTA or DTPA, binds a metal, preferrably Gd, having at least one unpaired electron. Any carboxoyl groups not involved in chelation are bound to a reduced lower carbohydrate having between 3 and 5 carbon atoms. Such compositions are useful for enhancing the contrast of Magnetic Resonance images.
