Deuterium (2H) MRS imaging (DMRSI) enables us to measure both the cerebral metabolic rate of glucose and TCA cycle rate and to image brain tumor with an excellent contrast. It is common to apply two sets of 2H and 1H RF coils for performing DMRSI, resulting in coil complexity and RF interference. We introduce an 8-channel 2H-1H dual-frequency loop coil array with LC tanks, enabling each loop coil being tuned to 2H and 1H resonant frequencies simultaneously. We have constructed a prototype head coil for human brain applications at 7 Tesla and validated the coil via benchtop and imaging tests.
