In this study, recently proposed diffusion tensor magnetic resonance electrical impedance tomography (DT-MREIT) is compared with magnetic
resonance conductivity tensor imaging (MRCTI) using simulated measurements generated by means of a finite element model. Both methods are
used to reconstruct conductivity tensor images of an anisotropic conductivity distribution. In DT-MREIT, extra cellular conductivity and diffusivity
ratio (ECDR) is recovered from its transverse gradient. In MRCTI, the conductivity tensor is reconstructed from two current profiles by using
anisotropic B sensitivity (AB S) method with a stronger regularization. Reconstructed conductivity images suggest that MRCTI provides better
accuracy than DT-MREIT, at lower SNR levels.
