The RF-coils of small-animal scanners often limit the range of accessible nuclei to single- or double-nuclear scanning. Here, a multi-tuneable RF-coil design is investigated. The design comprises a butterfly-type RF-coil for 1H, and a multi-tuneable coil for X-nucleus imaging. The coil assembly is tested in a 7 T scanner. 1H and X-nucleus field maps show good matching between the simulation and experiment. Imaging and spectroscopy experiments provide well-resolved images as well as distinctive spectral peaks corresponding to the phantom compounds. The presented imaging method with single coil assembly is considered a promising expansion of heteronuclear imaging.
