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.
