Özet

In this study, a Diffusion-Weighted (DW) Spin Echo (SE) based pulse sequence with current injection is proposed to combine data acquisitions of theDiffusion Tensor (

), current-induced magnetic flux density

and the magnetohydrodynamic (MHD) flow imaging. The current density distribution(

) can be estimated from the measured

using the MRCDI method and the conductivity tensor can be reconstructed from the acquired

and theestimated

using the DT-MREIT method. The acquired results of an experimental phantom with anisotropic diffusion using DW-SE pulse sequenceshows that the proposed method could provide multi-contrast imaging based on multiple physical properties.
