This work presents a new method for B0 inhomogeneitycorrected reconstruction of J-resolved (multi-TE) MRSI datawith limited k-space coverage. A constrained reconstruction formulation was proposed to simultaneously reconstruct the data at all TEs, using a joint low-rank constraint that exploits the spatial-spectral-TE correlation in the data and a spatial constraint that exploits prior edge information from high-resolution anatomical images. Simulation and in vivo experiments using a customized 3D J-resolved EPSI acquisition have been performed to evaluate the proposed method. Experimental results demonstrated improved lineshape and SNR achieved by the proposed method over existing B0 correction methods.
