Fluorine MRI is becoming a powerful tool for studying drug distribution and metabolism. For such studies, transmit/receive RF structures, capable of providing anatomical information at the 1H frequency and drug distribution/metabolism at the 19F frequency are needed. Past approaches for accomplishing this purposes include coil swapping or dual tuned coils. From difficult repositioning logistics, difficult construction, or SNR loses, none such methods has proven ideal. A very simple and efficient RF structure (a solenoid coupled to a loop) is presented in this work, which can operate at both frequencies of interest through a simple opening/closing of a mechanical/electrical switch.
