Figure 3From: Evaluation of radial distribution of cartilage degeneration and necessity of pre-contrast measurements using radial dGEMRIC in adults with acetabular dysplasia Scatterplot of ΔR1 and corresponding radial T1 Gd . For all 3 subgroups, Tönnis grade 0 (A), Tönnis grade 1 (B) and Tönnis grade 2~3 (C), high correlations (r = −0.869 ~ −0.944, p < 0.001) indicated that T1Gd and ΔR1 are equally effective in evaluating cartilage status. The lines represent the linear regression fit.Back to article page
