Improved Motion Sensitized Driven EquilibriumiiMSDEjis a kind of T2-prep pulse with motion probing gradients. it can be widely used for clinical applications including black-blood vessel wall imaging , lower extremity MR venography , or suppression of flow artifacts in contrast-enhanced studies for brain metastasis detection . The purpose of this study was to investigate basic appropriate parameters and evaluate the feasibility of this technique as gFlow sensitive cine MR imagingh. Flow sensitive cine MR imaging with iMSDE pre-pulse allows visualization of flow phenomena very clearly, which was not able with conventional cine MR imaging.
