A three-element 1H-31P dual-tuned array for magnetic resonance spectroscopy at 4.7 T.

This work describes the construction and testing of a three-element, double-tuned receive array and transmit coils for 31P-1H spectroscopy and imaging. The receive coils were geometrically-decoupled, single-loop surface coils and the transmit coils were concentric saddle coils. The coils were used to examine a physiologically-modeled CNC-milled phantom. The receive coil array was able to improve SNR while also providing gross localization of the 1H and 31P signals.
