Adiabatic T ₁ and T ₂ sequences were evaluated with a 3 T clinical system. The optimal parameters for in vivo quantitative imaging of articular cartilage were determined on the basis of the evaluation of relaxation time maps and in order to minimize scanning time and power deposition and maximize image quality. The results show that adiabatic T ₁ and adiabatic T ₁ are suitable for in vivo quantitative assessment of articular cartilage at 3 T. The preliminary results are encouraging when the techniques were applied to discriminate normal and early osteoarthritis cartilage.
