Lumbar disc degeneration is an important cause of lower back pain, sedentary, prolonged-standing behavior accelerates its course. In this study we evaluate intervertebral disc degeneration quantified by T1ρ and T2 mapping magnetic resonance imaging in sedentary and long standing populations compared with a healthy control group matched for age. We conclude that prolonged-standing is more likely to affect the L1 / 2 level discs, while sedentary is more likely to affect the lower segment discs (L4 / 5 and L5/S1).
