The hypothesis was tested that T1ρ relaxation time combined with the disc height in patients with disc degenerative disease (DDD) can detect painful discs non-invasively. Mean values for both biomarkers individually exhibited significant differences between non-painful and painful discs. The combination of biomarkers improved the predictive value to 95% (area under the curve from a ROC analysis). The long-term objective of this study is to evaluate quantitative and non-invasive biomarkers of disc degeneration in patients with lower back pain.
