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.
