Recently, it is shown that the magnetohydrodynamic (MHD) flow has potential in clinical applications. In addition, diffusion tensor imaging (DTI) is widely used as an exclusive clinical diagnostic method. To obtain the MHD flow velocity distributions in three directions, twelve acquisitions with flow-encoding gradients and external current injection are needed. By choosing flow-encoding directions carefully, it is possible to obtain MHD flow velocity and DT distributions from the MR phase and magnitude images of the same acquisition. In this study, the MHD flow and DT data of an imaging phantom are acquired simultaneously using a spin echo based pulse sequence.
