Method of calculating the T2 mapping value. a In a sagittal slice of T1-weighted fast-field echo images, we select a central slice (white dotted line) that passed through the center of the weightbearing cartilage (blue line) surrounded by the anterior and posterior margins of the meniscus (yellow line). In addition to the central slice, we added two slices neighboring the central slice anteriorly and posteriorly. b The region of interest (ROI) was set at the weight-bearing full-thickness cartilage (red line) of the medial and lateral femoral condyle and medial and lateral tibial plateau on the central slice of the coronal image. The ROI was also set using the same method on both the anterior and posterior slice. Overall, the T2 mapping values of 12 ROIs were measured
