A three-element (1)H-(31)P 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 (31)P-(1)H 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 (1)H and (31)P signals.
