Comparison of MRSI methods in vivo. (a) MRI of an axial supra-ventricular slice with positioning of outer volume suppression slices and voxel location of spectra shown below, (b) g-factor map for SENSE reconstruction. Spectroscopic images of inositol (Ins), choline (Cho), creatine (Cr) and N-acetyl-aspartate (NAA) (TR/TE: 2 s/ 11 ms, voxel size: 3 cc) using conventional PEPSI (c), SENSE-PEPSI (d), LBW-PEPSI (e) and single-shot PEPSI (f). The selected spectra on the right display the superimposed LCModel fit and the estimated baseline in the spectral range from 1.8 to 4 ppm.
