Cartilage T₂ relaxometry values are previously shown to be correlated to incidence OA, however prognostic ability of T₂ is not yet established. In this study, an automatic deep learning method is built using 3921 manually segmented images and T₂ was evaluated on entire Osteoarthritis Initiative Dataset (N=25,729). The proposed automatic T₂ quantification was shown to be interchangeable with human process and significant association between elevated T₂ and future incidence of OA was observed. The results of this study prove the prognostic ability of this compositional MRI technique on the larger sample ever analyzed.
