 Abstract: An overdiscrete reconstruction for in-vivo 3D Echo-Planar Spectroscopic Imaging (EPSI) data is used for SNR improvement and voxel bleeding reduction. We propose the estimation of a B field map, which is needed for the reconstruction, using the residual water signal in the dataset. A mean SNR enhancement of a factor of 2.8 was achieved for NAA and comparable reconstruction results were obtained with both the measured and the estimated B field maps.
