Magnetohydrodynamic (MHD) flow occurs due to the Lorentz force formed by the interaction between the static magnetic field of the MR scanner and the externally injected electric current. The MR based imaging of MHD flow has become a research field of interest recently. The MHD flow can be extracted from the MR phase images obtained using a pulse sequence with flow-encoding gradients. In this study, the MHD flow distributions of a simulated model and a homogeneous experimental phantom are obtained. The MHD velocity contrast images reconstructed using simulated and experimental measurements are consistent.
