To capture anatomical information and dynamic changes of different metabolic activities in the brain or other organs using a singular RF coil, we developed a loop RF surface coil design with a wide tune-match isolation and active tune circuitry for proton ( 1H) MRI, and interleaved deuterium ( 2H) and oxygen ( 17O) MRS measurements at 16.4T. We obtained static 1H MRI and performed interleaved dynamic 2H and 17O measurements in phantom studies. Results showed proficient proton imaging and quasi-stable 2H and 17O signals with rapid acquisition, indicating the potential of the design for robust high temporal resolution metabolic and anatomical imaging applications.
