A dual tuned head coil for combined 35Cl/ 23Na imaging is presented. For evaluating sensitivity optimization, two versions were built: one with a 23Na trap in the 35Cl resonator, one without. By including 23Na traps into the 35Cl resonator, the B1 efficiency of 35Cl versus 23Na can be controlled. The version with 23Na traps was evaluated in phantom and in vivo imaging. Both channels show good B1 efficiency and SNR performance. The presented setup allows for combined 23Na/ 35Cl MRI without repositioning of the patient.
