An intrinsically dual tuned single element antenna providing a congener resonance behavior is utilized within a four channel setup for combined 23Na and 1H MRI at 7T. The antenna is based on the composite right-/left-handed transmission line technique with short circuited line terminations. The array shows a homogeneous B1-field distribution for both resonances while the specific absorption rate is evenly distributed along the antennas.
