The aim of this study was to determine the association of T1 and T2 relaxation times and dGEMRIC to findings of arthroscopy, considered to be the gold standard for OA diagnosis. qMRI parameters were assessed at 3T in 10 patients. After imaging, arthroscopic cartilage grading was performed according to the International Cartilage Repair Society (ICRS) classification system. According to the results, qMRI parameters were not related to arthroscopic grading and may detect changes in cartilage tissue quality more sensitively as compared to arthroscopy.
