Quantitative MRI in early intervertebral disc degeneration: T1rho correlates better than T2 and ADC with biomechanics, histology and matrix content
Fig 5
Bar graphs showing mean ± SD post-to-pre differences (mean difference of sample paired post-experiment value to pre-experiment differences) for all three experimental groups.
Results are shown of the T2 (a) and T1rho (b) values in the nucleus and ADC in the outer-annulus; anterior (c), lateral (d) and posterior (e). PBS clearly had the least influence on quantitative MRI values for all three parameters, whereas 0.25 and 0.5 Cabc show larger loss of signal in the nucleus. Asterisk (*) indicates p-values below 0.05.
