摘要: Deuterium (2H) double-quantum filtered (DQF) NMR spectroscopy of nucleus pulposus (NP) tissues from human intervertebral discs is reported. The DQF spectral intensities, DQ build-up rates, and DQF-detected rotating-frame spin-lattice relaxation times are sensitive to the degree hydration NP tissue, display a monotonous correlation with age between 15 80 years. implications this work that changes in water dynamics as detected via may be used probe tissue degeneration NP, particularly early stages which most standard methods not sensitive.
