The aim of this project was to develop a triple resonant 1H/23Na/35Cl coil system for investigations on a rat stroke model without the need to exchange resonators during the measurements. The newly-developed coil system was composed of a linear 1H birdcage resonator and a double-tuned 35Cl/23Na surface coil. 1H imaging capability enabled the use of standard stroke sequences such as diffusion- and T2 weighted MRI. The coil performance was successfully tested on a 1H/35Cl/23Na-phantom. First brain images at 5 days after stroke confirmed the excellent coil performance for in vivo imaging.
