Fig. 1. Superselective transarterial radioembolization for hepatocellular carcinoma (HCC) close to the extrahepatic organs. (A) An arterial phase magnetic resonance (MR) image shows a 5-cm diameter HCC abutting the duodenum (arrows). (B) Coronal MR image shows the mass are also close to the gallbladder (arrowhead) and ascending colon (arrows). (C) Post-treatment positron emission tomography-computed tomography scan shows dense uptake of Y90 only in the tumor and adjacent hepatic parenchyma. (D) Follow-up computed tomography scan shows complete response of the tumor without any damage to the extrahepatic organs.
