Gadoxetic acid enhanced mDIXON liver MRI has excellent utility for diagnosing hepatocellular carcinoma; however, it often suffers from ghosting flow artifacts from aorta due to increased signal by contrast enhancement. To solve this problem, we attempt to use motion-sensitized driven-equilibrium (MSDE) for reducing through-plane flow artifacts particularly in dynamic contrast-enhanced studies. We showed the effect of MSDE in reducing through-plane flow artifacts particularly in dynamic contrast-enhanced studies. Two types MSDE schemes (MSDE and iMSDE) could significantly decrease flow signals and could therefore reduce flow artifacts sufficiently. In current sequence, iMSDE would be better for clinical studies because of its less sensitivity to field inhomogeneities.
