RF coil operation at 7T is fraught with technical challenges, making expansion of 7T into clinical imaging difficult. In this work, a microstrip transmission line and a wire loop coil were combined to form a double-nuclear RF coil array for proton magnetic resonance imaging and carbon magnetic resonance spectroscopy at the ultrahigh magnetic field strength of 7T. Network analysis revealed a high Q-factor and excellent decoupling between the coils. Proton images and carbon spectra were acquired with high sensitivity. The successful testing of this novel double-coil array demonstrates the feasibility of this design for multi-nuclear studies at 7T.
