We propose a single-shot isotropic diffusion-weighted magnetic resonance spectroscopy (DW-MRS) sLASER-based sequence which enables single-shot measurement of metabolite apparent diffusion coefficient (ADC) at relatively short diffusion times and reasonable echo times in the human brain at 7T. Five brain metabolites and water ADC values were measured in two brain regions that differs significantly in white (WM) and grey matter (GM) content. Significantly higher ADCmetabolites and lower ADCwater were observed in WM compared to GM, illustrating microstructural tissue-specific differences.
