Transjugular intrahepatic portosystemic shunt (TIPS) is
non-surgical method of portal decompression to treat
major complications of portal hypertension. Currently,
the combination of Doppler ultrasound and invasive
portosystemic pressure measurements are applied to
monitor patients before and after TIPS placement. An
alternative operator-independent and non-invasive
technique would be highly desirable. In this study we
demonstrate the feasibility of 4D-flow MRI for
qualitative and quantitative analyses of hepatic blood
flow before and then 2 and 12 weeks after TIPS
placement. 4D flow MRI is feasible for longitudinal
hemodynamic monitoring of the blood flow in the portal
vein and the TIPS stent.
