In this study, a Diffusion-Weighted (DW) Spin Echo (SE) based pulse sequence with current injection is proposed to combine data acquisitions of the Diffusion Tensor ($$$\overline{\overline{D}}$$$), current-induced magnetic flux density $$$B_z$$$ and the magnetohydrodynamic (MHD) flow imaging. The current density distribution ($$$\overline{J}$$$) can be estimated from the measured $$$B_z$$$ using the MRCDI method and the conductivity tensor can be reconstructed from the acquired $$$\overline{\overline{D}}$$$ and the estimated $$$\overline{J}$$$ using the DT-MREIT method. The acquired results of an experimental phantom with anisotropic diffusion using DW-SE pulse sequence shows that the proposed method could provide multi-contrast imaging based on multiple physical properties.
