Biochemical assessment is critical for early detection and staging of hip articular cartilage damage, as well as to predict risk for progression. We employed the principles of magnetic resonance fingerprinting to explore the feasibility of simultaneous T1 and T2 mapping in clinically feasible scan times. In addition to a PD image, our method quantified T1 and T2 with a 0.8x0.8 mm2 in-plane resolution (scan time of 1:20 min per slice). By enabling a fast comprehensive morphological and biochemical assessment, we hope to improve assessment and staging of cartilage damage, predict risk for progression and impact patient management decisions.
