This study aims to quantify the loading-modified T1 in articular cartilage using a canine model of early osteoarthritis (OA) at different degradation stages, at a 17.6┬Ám resolution and with the use of Gd contrast agent. Both lesion and mechanical compression were found to alter T1 in cartilage at each sub-tissue zone and topographically, which provide a better understanding of the MRI properties of cartilage during joint loading. This result could help to design effective protocols in clinical MRI to better detect and manage the osteoarthritic diseases.
