A dual-tuned hybrid resonator coil for high field multinuclear MRI/MRS combines both the TEM and the BC designs, such that the mode splitting is significantly increased. The coil includes TEM elements and BC coil windows, where the TEM elements are positioned in each of the windows and oriented orthogonally thereto. This arrangement allows retaining all of the advantages of the TEM technology at high frequencies, while drastically reducing mode mixing and the associated shading artifact.
