Preliminary
results from a dual tuned 23Na sodium 1H proton knee coil are presented. A
multiple ring birdcage design has been employed providing high sensitivity
and uniformity to both nuclei without the need for frequency traps. Both coil
sections are circularly polarized quadrature coils with direct drive cable
connections. Cables are routed to a common potential node avoiding the need
for baluns and avoiding parasitic cable loops. Registered images are
presented for both sodium and proton acquisitions, avoiding the need to
change the RF coil during the study
