Proposed method offers spectra with sufficient quality for the quantification of the main metabolites (choline, creatine, NAA). Individual correction of the local resonant frequency can be performed even for a small voxels. This correction can be done by an evaluation of the water signal position. Moreover obtained CSI spectra do not need phase correction. Therefore it is possible to calculate a sum spectrum from a certain area which corresponds with certain anatomical structure. Such spectrum offers a higher SNR and better spectral resolution than SVS spectrum.
