Total liver volume was calculated using dedicated software (HepaVision®, MeVis, Germany) by tracing around the margins of the hepatic parenchyma on selected transversal slices. Slices in between were interpolated. Large vessels as the inferior vena cava and extrahepatic portal vein were excluded. The cross sectional area (cm2) within the region of interest was determined, and all individual areas were summed yielding the total liver volume (cm3).
