Patients with early-stage hepatocellular carcinoma (HCC) usually have no symptoms, so the disease is often advanced by the time it is diagnosed. HCC is resistant to chemotherapy, and the effectiveness of external beam radiation in treating the disease is limited. Surgical resection and liver transplantation offer a potential for cure. However, most patients have unresectable disease. This article discusses the less invasive image-guided ablative and embolization therapies that offer patients palliation of symptoms as well as the potential for increased survival. Radiologic technologists need to know the techniques of these procedures as well as normal and variant anatomy in patients and how those factors affect the delivery of therapeutic agents.

早期肝细胞癌（HCC）患者通常没有症状，因此该病在确诊时往往已发展到晚期。HCC对化疗耐药，外照射放疗治疗该病的效果有限。手术切除和肝移植提供了治愈的可能性。然而，大多数患者的疾病无法切除。本文讨论了侵入性较小的影像引导下的消融和栓塞治疗，这些治疗可为患者缓解症状并有可能提高生存率。放射技师需要了解这些操作技术以及患者的正常和变异解剖结构，以及这些因素如何影响治疗药物的递送。本文是一篇定向阅读文章。你能否获得用于继续教育学分的定向阅读测验取决于你的兴趣领域。要获取其他测验，请访问www.asrt.org/store。
