The T1 profiles of articular cartilage as the function of the Gd concentrations, plotted using the relative tissue depth (0 = articular surface, 1 = cartilage-bone interface). The native tissue at (a) 0% strain (not compressed), (c) 20% strain, (e) 40% strain. The degraded tissue at (b) 0% strain (not compressed), (d) 28% strain, (f) 50% strain. The error bars are the standard deviations.
