Variable quantitative hepatic imaging biomarkers including
pharmacokinetic parameters of hemodynamics and hepatocellular uptake function,
R2* and fat fraction, apparent diffusion coefficient (ADC), liver stiffness
were obtained from the patients with chronic hepatitis using MR imaging. The
change and interrelation of these imaging biomarkers in the course of chronic
hepatitis were evaluated quantitatively. Portal venous inflow and
hepatocellular uptake function correlated well with liver stiffness, meanwhile,
ADC showed weak correlation. Arterial compensation, decreased blood flow speed
and volume were observed in the patients with decreased portal venous inflow. No
significant correlation was observed between liver stiffness and R2* or fat
fraction.
