Assessment of Subchondral Bone Marrow Lipids in OA Patients at 3T

Ligong Wang¹, Nouha Salibi², Gregory Chang, Michael Recht, Ravinder R. Regatte

This work reported the saturated lipid signals and unsaturated lipid indices in different compartments of femoral-tibial bone marrow in OA patents at 3T. There were significant differences among different compartments of femoral-tibial bone marrow only at 2.03 ppm for saturated lipids (P < 0.002). The tibia has relatively higher saturated lipids compared to the femur. The femur has a relatively higher unsaturated lipid index compared to the tibia.
