Figure 5. An 84-year-old man with hepatocellular carcinoma in the right lobe of the liver. Conventional digital subtraction angiography of the arterial phase (A) and parenchymal phase (B) showed right hepatic artery branches and tumor stain with a diameter of 40 mm in the right lobe of the liver (arrow). Separation of the right hepatic artery branches was poor. It was difficult to identify the feeding vessel of the tumor. Volume-rendering image of the CBCT in frontal (C) and right oblique (D) view obtained the three-dimensional information in the right hepatic artery and the branches could be separated. Coronal multiple planar reconstruction image of the CBCT (E,F) showed the hypervascular tumor and A7 branches of the right hepatic artery (arrow) as feeding arteries.
