摘要：
NMR spectroscopy is performed on intervertebral disc tissue. Extent of degeneration is determined based on the NMR spectroscopy. Correlation between NMR spectral regions and at least one of tissue degeneration and pain are made. Accordingly, NMR spectroscopy is used to determine location and/or extent of at least one of degeneration or pain associated with a region of tissue, such as for example in particular disc degeneration, or discogenic pain. NMR spectral peak ratios, such as between N-Acetyl/cho and cho/carb, are readily acquired and analyzed to predict degree of tissue degeneration and/or pain for: tissue samples using HR-MAS spectroscopy and larger portions of anatomy such as joint segments such as a spine, using clinical 3T MRI systems with surface head or knee coils and tissue regions such as discs within spines of living patients using 3T MRI systems with a surface spine coil, thus providing a completely non-invasive diagnostic toolset and method to image and localize degeneration and/or pain.
