A Representative sagittal 3D spoiled gradient echo MRI images of the ACL of an OA (left) and healthy (right) subject with overlaid T1rho colormaps. Note higher and more heterogeneous values of T1rho in the OA subject. B As above but with T1rho colormaps of the PCL. Note higher T1rho values in proximal part of the PCL in the OA subject. C Variation in T1rho within the cruciate ligaments of an OA (left) and healthy (right) subject. Note increased variation/heterogeneity of T1rho values throughout the ACL of the OA subject
