Fig. 3A–C.

The figure shows the plots comparing radiological and surgical assessments of cartilage damage for acetabular subregions AP (left column) and SP (right column), which face the highest likelihood of damage in hips with FAI [5]. Planar dGEMRIC map-dependent and map-independent radiological assessment data are displayed side by side in each plot. The mean values are connected by either solid or dashed lines and the error bars indicate ± SD. (A) The figure shows the modified Outerbridge grade (radiological) versus Beck’s grade (surgical); (B) the dGEMRIC index (radiological) versus Beck’s grade (surgical); (C) the dGEMRIC index (radiological) versus the modified Outerbridge grade (radiological), examining intermetric consistency in radiological assessment.
