Placements of lipid saturation bands not only demand a skillful MRSI scanning operation but also restrict the full brain MRSI coverage. Therefore, MRSI acquisition without lipid suppression while doing post-removal of lipid becomes clinically attractive and valuable. In this work, we propose to integrate hybrid CSI/EPSI acquisitions with L2 regularization for fast lipid removal of MRSI. The hybrid CSI/EPSI acquisitions rely on the same excitation and refocusing evolution with the modified CSI and EPSI sequences. Phantom and in-vivo brain studies demonstrate the effectiveness and low computational cost of the proposed method.
