In this study, a balanced steady-state free precession (SSFP) sequence with motion-sensitized driven-equilibrium (MSDE) preparation was used as an alternative technique for magnetic resonance cholangiopancreatography (MRCP).@@T2-weighted MRCP was associated with poor visualization of the biliary systems due to excreted Gd-EOB-DTPA, as previously reported. Use of MSDE-balanced MRCP resulted in higher CNR and better visualization of biliary structures than T2-weighted MRCP. Moreover, problematic vesselfs signals, such as PV and HV, were sufficiently suppressed by MSDE technique.@@In conclusion, we demonstrated the usefulness of MSDE-balanced MRCP sequenced in Gd-EOB-DTPA post-contrast study.
