A novel multifrequency-tuned transceiver array for human-brain ³¹P-MRSI at 7 T.

ABSTRACT:

Purpose

Phosphorus-31 (³¹P) MR spectroscopy imaging (MRSI) at 7 T is a powerful tool for investigating high-energy phosphate metabolism in human brains with significantly improved signal-to-noise ratio (SNR) and spectral resolution. However, this imaging technique requires dual-frequency radiofrequency coil for performing brain anatomical imaging and B₀ shimming at proton (¹H) operation frequency, and ³¹P MRSI at lower operation frequency. Herein, we introduce a novel ³¹P-¹H dual-frequency radiofrequency coil design using a double-tuned and double-matched (DODO) coil that does not require complex circuitry or two coil layers and exhibits similar imaging performance as to single-frequency control coils for both ³
