  • Method for the determination of iron stores in organic tissue and NMR spectrometer for performing this method
    Patent number: 4889125
    Abstract: A method for the determination of iron stores in organic tissue consists in measuring the relaxation time of deuterium included in said tissue by magnetic resonance spectroscopy.
    Type: Grant
    Filed: June 5, 1987
    Date of Patent: December 26, 1989
    Inventors: David M. Doddrell, Michael G. Irving
  • Method for determining the turnover of organic material in living tissue and NMR spectrometer for performing this method
    Patent number: 4889126
    Abstract: A method for determining the turnover of organic material stored in living organic tissue consists in that the deuterium content of the stored material is artificially modified from natural abundance and monitored as a function of time by measuring the CHD-signal by means of magnetic resonance spectroscopy. E.g., for determining the fat turnover in living beings, the deuterium content of the body fat may be increased by administering to the living being drinking water contaiing 10% D.sub.2 O for 28 days. Thereafter, the decrease of the deuterium content of the body fat is monitored while normal water is administered. The loss of .sup.2 H from body fat is an indication for the body fat turnover.
