Figure 3


Fig. 3 —Graph shows contrast phase versus mean signal intensity for portal trunk, liver parenchyma, and hepatic veins. Signal intensity of portal trunk increases steeply over late hepatic arterial phase (HAP) and then decreases gradually. Significant differences in mean signal intensity (p < 0.05) exist between all phases but not between late HAP and portal venous phase (PVP). Signal intensity of liver parenchyma increases constantly over portal venous phase and then decreases slightly in equilibrium phase (EP). Significant differences in mean signal intensity (p < 0.05) exist between all phases but not between late HAP and equilibrium phase or between portal venous and equilibrium phases. Signal intensity of hepatic veins increases steeply over portal venous phase and then decreases slightly in equilibrium phase. Significant differences in mean signal intensity exist between all phases (p < 0.005). Pre = before contrast injection.
