We have developed a dual-tuned proton/sodium knee RF coil at 7T and obtained high-resolution sodium MR imaging and T2 mapping of human knee cartilages within clinically acceptable time. Further studies on coil optimization and reproducibility of sodium concentration measurement should be followed for the clinic application.
