  • Method of diagnosing colorectal adenomas and cancer using proton magnetic resonance spectroscopy
    Patent number: 6821784
    Abstract: Two dimensional COSY magnetic resonance spectroscopy of human stool can be used in a non-invasive method of detecting the presence of colorectal cancer. The spectrum of a patient's stool is compared with that of stool from non-cancerous subjects, observed differences in spectra being indicative of cancer.
    Type: Grant
    Filed: November 16, 2001
    Date of Patent: November 23, 2004
    Assignees: The University of Manitoba, National Research Council of Canada, Board of Regents, University of Texas System
    Inventors: Tedros Bezabeh, Ian C. P. Smith, Charles Noah Bernstein, Bernard Levin, Constance Johnson
  • Method of diagnosing colorectal adenomas and cancer using proton maggnetic resonance spectroscopy
    Publication number: 20030148260
    Abstract: One dimensional proton magnetic resonance spectroscopy of human stool can be used as non-invasive method of detecting the presence of colorectal cancer and/or clinically significant adenomas. The spectrum of a patient's stool is compared with that of stool from non-cancerous subjects, observed differences in spectra being indicative of cancer and/or clinically significant adenomas. In a preferred method, the stool sample is mixed with a buffer, the resulting suspension is centrifuged and the supernatant is subjected to magnetic resonance spectroscopy.
