Maximizing the signal-to-noise ratio (SNR) in in vivo cardiac phosphorus-31 magnetic resonance spectroscopy (³¹P-MRS) remains a major challenge in investigations of human myocardial energy metabolism. Here, we demonstrate that with a dual-tuned ¹H/³¹P coil array with 4 elements, it is feasible to achieve a higher SNR and a more homogeneous receive sensitivity distribution over the region of interest for cardiac ³¹P-MRS at 3 Tesla than with a standard linear single-turn ³¹P surface coil. Furthermore, the 4 channels available for ¹H signal reception allow for cardiac cine ¹H-MRI with parallel imaging.
