Purpose: To investigate characteristic spectral parameters and quality features of in-vivo 1H-MRS at 7.0 T and to measure metabolite concentrations in an intra-individual comparison to results obtained at 3.0 T and 1.5 T. Methods: Single-voxel proton MR spectra of parietal white matter were obtained at an ultra-highfield whole body MR unit operating at 7.0 T (Achieva 7.0T, Philips Medical Systems) and at clinical whole body 3.0 T and 1.5 T MR systems (Achieva 3.0T and Intera 1.5T, Philips Medical Systems). Transmit/receive quadrature head coils were used at all field strengths, and the same 3 healthy volunteers…
