This study demonstrated T2 and T1rho profiles of talar dome and tibial plafond cartilage from male and female ballet dancers using angular-segmentation methodology for quantitative assessment of cartilage in vivo. The results in this study showed both T2 and T1rho relaxation time indicated the lowest value over the central weight-bearing portion, while they indicated relatively higher values in the anterior and posterior portion. These findings can be due to the combination of the magic angle effect which has higher influence on T2 value and early cartilage degenerative changes which are more sharply detected by T1rho value.
