title: Hydrogen-1, sodium-23, and carbon-13 MR spectroscopy of cartilage degradation in vitro.
abstract: Viable bovine nasal cartilage was examined with magnetic resonance (MR) spectroscopy. Digestion of the proteoglycan matrix by papain or trypsin was accompanied by substantial changes in carbon-13, sodium-23, and hydrogen-1 MR spectra and relaxation parameters, with C-13 MR spectra showing the most pronounced changes. These results indicate the potential of MR spectroscopy (and imaging) for noninvasive evaluation of cartilage disease and monitoring of patients with degenerative joint diseases.
