Both T2 and T1rho have been employed to evaluate
articular cartilage degeneration. The magic angle effect
in T2 relaxation is well understood. However, the
literature regarding T1rho relaxation mechanisms is
inconsistent. Some researchers reported much reduced or
negligible magic angle effect in T1rho, while other
researchers have reported significant magic angle effect
in T1rho relaxation. Furthermore, magic angle effects in
normal vs. abnormal cartilage are unknown. In this study
we aimed to systematically evaluate the magic angle
effect on T2 and T1rho in histological confirmed normal
and abnormal cartilage at 3T
