Claim 0:
1. A radiofrequency (RF) coil system for performing magnetic resonance imaging (MRI), magnetic resonance spectroscopy (MRS), or magnetic resonance spectroscopy imaging (MRSI) configured to be operated at multiple resonant frequencies, the coil system comprising:
at least one conductive loop and a capacitor forming an RF resonant antenna;
a tuning-matching circuit electrically connected to the RF resonant antenna to operate at multiple resonant frequencies across a desired operational range; and
two conductive legs electrically connecting the tuning-matching circuit to the RF resonant antenna and having a length selected to generate at least two selected resonant frequencies with a selected frequency difference.
