Figure 2

Radial distribution of T1 pre (A), T1 Gd (B) and ΔR1 (C) according to Tönnis grading. Compared to the Tönnis grade 0 subgroup, T1pre increased significantly in the superoanterior (p = 0.036) and posterior (p = 0.022) sub-regions in the Tönnis grade 1 subgroup and in the posterior sub-region (p = 0.001) in the Tönnis grade 2 ~ 3 subgroup; there was a significant decrease in T1Gd in the anterosuperior to superior sub-regions (p = 0.026 ~ 0.042) in the Tönnis grade 1 subgroup and a significant overall decrease (p = 0.001 ~ 0.020) in the Tönnis grade 2 ~ 3 subgroup; ΔR1 increased significantly in the anterosuperior to superoposterior (p = 0.012 ~ 0.042) and posterior (p = 0.042) sub-regions in the Tönnis grade 1 subgroup and there was a significant overall increase (p = 0.001 ~ 0.020) in the Tönnis grade 2 ~ 3 subgroup.
