Diffusion tensor magnetic resonance electrical impedance tomography versus magnetic resonance conductivity tensor imaging

2018-06-16
In this study, recently proposed diffusion tensor magnetic resonance electrical impedance tomography (DT-MREIT) is compared with magneticresonance conductivity tensor imaging (MRCTI) using simulated measurements generated by means of a finite element model. Both methods areused to reconstruct conductivity tensor images of an anisotropic conductivity distribution. In DT-MREIT, extra cellular conductivity and diffusivityratio (ECDR) is recovered from its transverse gradient. In MRCTI, the conductivity tensor is reconstructed from two current profiles by usinganisotropic B sensitivity (AB S) method with a stronger regularization. Reconstructed conductivity images suggest that MRCTI provides betteraccuracy than DT-MREIT, at lower SNR levels.
