A striking manifestation of the voxel-bleeding effect in MRSI in vivo is subcranial fat signal falsely appearing in a voxel in the center of the brain. We developed a localized filtering technique for the suppression of fat artefacts. Unlike k-space apodization techniques, we achieve artifact suppression without incurring fat signal spread at the edge of the object.
