The aims of this study are to compare T2 relaxation time and MTR and determine whether MTR map is useful to depict degeneration of patellar articular cartilage as well as T2 map or not. There was a good negative correlation between T2 relaxation time and MTR. MTR map could be useful to depict early degeneration of cartilage as well as T2 mapping and has a potential as an adjunct to T2 relaxation time in early diagnosis of OA.
