Flow-sensitive 4D MRI provides complete volumetric and temporal coverage of hepatic venous and arterial hemodynamics in liver cirrhosis patients before and after TIPS-stent-graft implantation. Flow-sensitive 4D MRI provided a complete picture of pre- and post-interventional hepatic hemodynamics with additional information compared to Doppler US in liver cirrhosis after TIPS-stent-graft implantation. TIPS-stent-graft implantation resulted in altered hemodynamics and increased velocities and flow volume in the venous as well as hepatic arterial system. Compared to Doppler Ultrasound, maximum and mean velocities and vessel area tended to be lower in MRI while flow volume, resistance and pulsatility indices were similar.
