Figure 1a. (a) Frontal and (b) caudal 3D CT angiographic images of the peripheral branches of the hepatic artery in a 70-year-old man with cirrhosis of the liver. This case belongs to group D. The images were rated as excellent because the peripheral branches of the hepatic artery are clearly depicted from the subsegmental (arrows) to the sub-subsegmental level (arrowheads).

Figure 2a. (a) Frontal and (b) right anterior oblique 3D CT angiographic images of the peripheral branches of the hepatic artery in a 72-year-old woman who had hepatocellular carcinoma. Dynamic CT was performed because the patient was suspected of having hepatocellular carcinoma on the basis of the results of abdominal US. This case belongs to group C. Tumors are seen in S8 (T1) and S6 (T2) of the right lobe. The feeding arteries of each tumor are clearly depicted. In b, there appear to be two feeding arteries (arrows) for the S8 tumor. The visual evaluation was good.

Figure 3. Three-dimensional CT angiographic image of the peripheral branches of the hepatic artery in a 64-year-old woman who had hepatocellular carcinoma. Dynamic CT was performed for screening and depicted hepatocellular carcinoma. This case belongs to group A. The images of this patient were rated as fair because the subsegmental branches of the hepatic artery were indistinct (arrowheads).

Figure 4. Three-dimensional CT angiographic image of the peripheral branches of the hepatic artery in a 68-year-old woman with cirrhosis of the liver. This patient was excluded from analysis because the portal vein branches were visualized in the periphery (arrowheads), which prevented evaluation of the hepatic artery. This case belongs to group B.
