The higher SNR found at 7T allows for more diagnostic applications for nuclei other than hydrogen. In particular, sodium imaging has been found to be useful in characterizing cartilage degeneration in the joints, with the focus primarily on the knee. In an effort to design RF coil hardware optimized for these x-nuclei applications, a 12-rung birdcage transmitter and 15-channel receive-only array coil has been developed for sodium imaging of the knee.
