Normal healthy volunteers (n=10; 5m, 5f) were scanned at both 1.5T and 3T using an acquisition weighted chemical shift imaging sequence (AW-CSI). A voxel of interest was selected anatomically, and spectral peaks were quantified using jMRUI to determine the signal to noise ratio (SNR). There was a significant increase in SNR (~100%) at 3T compared with 1.5T which could be used to increase the spatial or temporal resolution of 31P cardiac spectra.
