Figure 2. Radiation segmentectomy of a 3.5 cm HCC in a 71-year-old-man with hepatitis C cirrhosis. (A) Coronal contrast-enhanced computed tomography image demonstrates an arterial phase hyperenhancing HCC. (B) Right hepatic digital subtraction arteriogram with contrast injection via the microcatheter located in the distal segment 8 artery at the time of radioembolization. Note the tumor vascularity (asterisk). (C) Coronal contrast-enhanced computed tomography image 6 months after radioembolization shows a wedge-shaped region of necrosis subtending the treated artery. Note the bifurcating artery corresponding to the artery depicted in C (arrow).
