The creation of a transjugular intrahepatic portosystemic shunt (TIPS) influences hepatic blood flow dynamics. TIPS-related changes of diffusion-weighted imaging based intravoxel incoherent motion (IVIM) parameters at 1.5 T were investigated in liver parenchyma of cirrhotic patients. An increase of the IVIM perfusion fraction was found, indicating improved microvascular flow within the liver tissue after decompression of the portal vein. Diffusion parameters were not significantly influenced by TIPS-creation.
