Figure 1

Trans-axial post-contrast T1FS MR image of the femoral condyles showing the direction of sectioning perpendicular to a line joining the dorsal aspects of the medial and lateral femoral condyle with a width of 4.4 mm. Optimally, the central slice of the lateral femoral condyle (broken line) is used for estimating the reference values, See Figure 2. Sections adjacent to the inter-condylar area and at the joint margins may contain partial volume information from soft tissue structures (white lines). Four sections of the medial femoral condyle (between section 3 and 8) are available for the measurements of bone marrow lesions (BMLs). Note that the medial condyle decreases ventrally resulting in decreasing bone marrow area on sagittal images medially.
