Abstract

Preliminary results of 'new clinical applications of functional imaging of the liver are reported. In 20 healthy volunteers portal flow measurement with Doppler US at the level of right, left portal branch and main portal trunk, showed the preferential distribution in baseline conditions of portal flow to the right liver (about 68%) as compared to the left portal branch. This influenced MRI volumetry of right liver as compared to left liver. After meal intake, flow increase was significantly higher at the level of left portal branch suggestive for a 'functional reserve' in left liver. Portal flow physiology was examined in preparation of portal imaging before and after portal vein embolization, a procedure performed preoperatively before enlarged hepatectomies.
