4D flow MRI provides valuable information on blood flow
velocities with full spatial (3D) and temporal (cardiac
cycle) coverage, which can be applied to volumetric and
functional evaluation of liver hemodynamics in liver
cirrhosis patients. This study reveals mean velocities
in portal venous and arterial systems of liver tend to
be lower for liver cirrhosis patients and appear to be
wider distributed. This result is showed by plotting
velocity histograms of healthy and pathologic groups
with selected parameters based on sensitivity test.
Quantitative analysis of liver hemodynamics using
flow-sensitive 4D MRI may be a standardized method to
complement the diagnosis in liver cirrhosis.
