Due to the specific compartmentation of brain metabolites, diffusion-weighted magnetic resonance spectroscopy opens unique insight into neuronal and astrocytic microstructures. The apparent diffusion coefficient (ADC) of brain metabolites depends on various intracellular parameters including cytosol viscosity and molecular crowding. When diffusion time (t(More)
Due to their pure intracellular compartmentation, the translational diffusion of brain metabolites in vivo depends on the intracellular environment, including viscosity, molecular crowding and subcellular structures. However, as the diffusion time is increased, metabolites have enough time to significantly encounter cell boundaries, so that cell size and(More)
The brain is one of the most complex organs, and tools are lacking to assess its cellular morphology in vivo. Here we combine original diffusion-weighted magnetic resonance (MR) spectroscopy acquisition and novel modeling strategies to explore the possibility of quantifying brain cell morphology noninvasively. First, the diffusion of cell-specific(More)
