An axially oriented loop resonator is used to obtain 1H co-registration images for 31P spectroscopic imaging at 7T using a 12 leg 31P birdcage coil. The 8 cm diameter loop provides extended coverage from crown to brain stem with low coupling to the 31P volume coil. This approach provides a useful alternative to the careful subject positioning required with two coils or the construction of a double tuned resonator.
