Role of stereotactic body radiation therapy for hepatocellular carcinoma

Figure 4 Case of hepatocellular carcinoma located in the hepatic hilum. Surgical resection would have required a right lobectomy. Percutaneous ablative therapy was impossible due to involvement of the biliary system and large vessels near the tumor. Axial and coronal views of a tumor with partial lipiodol deposit (A and B, arrows). Axial and coronal views of radiation dose distribution (C and D). The isodose lines (white lines) from inner to outer represent 40, 30, 20, and 10 Gy, respectively.
