Fig. 3. Correlation was seen between JSW and cartilage thickness (0 Fig. 3. Correlation was seen between JSW and cartilage thickness (0.50), and acetabular plate thickness and trabecular density (−0.45) for 0.5mm CT data, 0.50 and −0.49 respectively for 1.5mm CT data. Example volumes are given from CT as joint space (yellow), femoral plate (purple) and acetabular plate (red); from MRI as femoral (green) and acetabular (blue) cartilage.
