Fig. 2

Mean values of T2* relaxation times in ms of all 144 cartilage regions of interest of the femorotibial joint. In each figure section the numbers 1 to 6 (x-axis) represent the segmentation in the frontal plane from lateral to medial (1-3: lateral joint compartment; 4-6: medial joint compartment). The segmentation of the cartilage in the sagittal plane is defined as anterior, intermediate and posterior (y-axis). The regions of interest are shown for a) the deep cartilage layer of the left knee b) the deep cartilage layer of the right knee c) the superficial cartilage layer of the left knee d) the superficial cartilage layer of the right knee
