Angle-dependent analysis of T1rho values of the superficial and deep layers at the (a) medial condyle, (b) trochlea, and (c) lateral condyle. There is angle dependence of T1rho profiles in each layer, with no influence of magic angle effect. T1rho values are higher in the superficial layer than the deep layer in most areas of the medial and lateral condyles. At the trochlea, T1rho values are higher in the superficial layer compared to the deep layer at above approximately −50°, and an inverse relationship appears below −50°, with higher T1rho values in the deep layer. Average T1rho values in the superficial layer of the femoral articular cartilage are higher than those in the deep layer on the (a) medial condyle, and (c) lateral condyle, with a statistically significant difference (p < 0.05)
