Figure 6. Perfusion imaging of liver lesions, calculated from triphasic scans.
Hepatocellular carcinoma (moderately differentiated, pathology proven). The pink color of the lesion indicates predominantly arterial inflow.
Note that the aorta is red and has a hepatic artery coefficient near 100% and portal vein coefficient of 0%. The portal vein is blue and has a hepatic artery coefficient of 0% and a portal vein coefficient of 100%.
