Fig. 3 Illustration of the volume of interest localization for diffusion-weighted magnetic resonance spectroscopy (left column) and the corresponding spectra (right column). (a) Corona radiata; (b) Posterior cingulate cortex. b0 denotes the spectrum acquired without diffusion gradient application, while b1-LR, b1-AP, and b1-HF represent spectra obtained with the diffusion gradient applied in the left-right, anterior-posterior, and head-foot directions, respectively
