Assessing portal vein (PV) hemodynamics is an essential part of liver disease management and liver surgery, yet the optimal methods of assessing intrahepatic portal vein flow have not yet been established.
This study investigated and used of 7-Tesla MRI with hemodynamic analysis for detecting small flow changes within narrow intrahepatic PV branches.
The result shows that　3D PC-MRI at 7-Tesla combined with 　hemodynamic analysis is a promising tool for assessment of intrahepatic portal vein flow and enables future studies in small animals to investigate portal vein hemodynamics associated with liver disease/postoperative liver recovery.
