The objective of this study is to evaluate T1ρ MRI as quantitative biomarker of disc degeneration in patients being treated for Lower Back Pain (LBP) by comparing it to invasive discography opening pressure. A significant and strong correlation exists between non-invasive MRI T1ρ values and in vivo opening pressure measurements. T1ρ is a quantitative measure of degeneration that is consistent across both control subjects and LBP patients.
