¹H-MRS is increasingly applied in many organs for non-invasive tissue characterization, e.g. for quantification of ectopic lipids. Spectroscopic examinations of the myocardium often suffer from limited spectral dispersion, thus limiting the metabolic information content. Applying a new 60-channel body-array receive coil, high quality spectra with superior dispersion as compared to previous setups are shown in this work. A single voxel PRESS technique was applied in 10 subjects. After higher-order shimming, linewidths of <20 Hz were obtained with high SNR in a clinically acceptable measuring time. High reproducibility and performance of the method may promote 1H-MRS applications in metabolic research and sports medicine.
