We have developed a multi-transceiver dual-tuned knee coil at 3T which provides high SNR and imaging depth for sodium and co-register of both proton and sodium imaging in a single session. The coil allowed us to acquire in vivo knee cartilage with high SNR in a clinically acceptable time (~30 minutes total session). Further studies on B1-phase shimming are essential to produce a homogenous B1 field and to test the accuracy and reliability of sodium concentration measurement in knee cartilage.
