The increase in the intrahepatic blood flow resistance
in chronic liver disease has been identified as one of
the most sensitive parameters to detect liver cirrhosis
progression. Portal vein liver perfusion is affected
very early during the liver diseases progression. In
this work we investigated the feasibility of selectively
visualizing the intrahepatic portal vein and estimating
its intrahepatic volume in healthy subjects and patients
with cirrhosis as a marker of liver perfusion, using a
new Arterial Spin Labeling technique without the need of
subtraction (TIR-ASL).
