Balanced steady state free precession (bSSFP) is a widely used MR sequence since it has high speed, high SNR, motion insensitivity and automatic eddy current compensation. Besides all these advantages, bSSFP sequence is susceptible B0 inhomogeneity and banding artifact occurs in certain off-frequency regions. In this paper, one of the correction methods, LORE-GN, is utilized to obtain transceive phase free from the distortions originating from B0 inhomogeneity. As an application, acquired transceive phase maps are used to obtain conductivity maps.
