The FLORET sequence was implemented to acquire sodium MRI of articular cartilage with and without fluid suppression by inversion recovery in the knee joint at 7T. Sodium FLORET images were compared to conventional 3D radial acquisition and showed an average increase of SNR of 30% and 77%, without and with fluid suppression respectively, measured in different regions of cartilage and for the same acquisition time.
