DTI has been used as a powerful tool for investigating
the anisotropic property of biological tissues. MR-based
electrical impedance tomography (MREIT) could visualize
the apparent tissue conductivity by measuring the one
component of magnetic flux density by the externally
injected currents. The diffusivity of water molecule and
electrical tissue conductivity depend on the anisotropic
orientation of tissue. The effective medium model
implies that the diffusion and electrical conductivity
tensor eigenvalues are connected through a linear
relationship. Combing DTI and MREIT techniques, we
propose a new method, DT-MREIT, which provides in vivo
anisotropic absolute conductivity tensor images of the
human body.
