Chemical shift artifacts in magnetic resonance electrical impedance tomography (MREIT) degrade the accuracy of the reconstructed conductivity. In this study, we investigated the use of the iterative decomposition of water and fat with echo asymmetry and least-squares estimation (IDEAL) algorithm to remove these artifacts in a simple fat/water phantom. The results demonstrate that this technique can be used to correct for chemical shift artifacts in MREIT.
