目的：探索肝细胞癌（ HCC）动脉化疗栓塞治疗（ TACE）过程中采用C臂CT的扫描方法及其应用范围。方法80例HCC患者于2012年9月至2013年3月在我院接受TACE治疗时行C臂CT扫描。以指导介入操作和评估TACE疗效为目的，探索C臂CT扫描方法，评价C臂CT的应用范围。结果在TACE治疗HCC中，C臂CT扫描使用稀释的非离子型造影剂，采用平扫、动脉早期、动脉实质期三个时相扫描，可以满足病灶的检出、供血动脉显示、异常供血动脉和动脉异常走行的显示需要，可以便捷、准确、全面地评估病灶存活肿瘤、碘油沉积、供血动脉栓塞是否完全等情况，即时评价TACE疗效的效果满意。 C臂CT扫描未明显增加X线辐射剂量，手术时间平均延长9?5min。结论在TACE治疗HCC过程中应用C臂CT扫描安全、有效，对于术前制定计划、术中指导操作以及术后即时评估疗效等有较大帮助。

Objective To explore the method of C arm CT imaging and its application range in transarterial chemoemboliza-tion ( TACE) therapy for hepatocellular carcinoma ( HCC) patients. Methods Eghity HCC patients receiving TACE therapy in our hospital during Sep. 2102 and Mar. 2013 were enrolled in the study. C arm CT imaging was applied during TACE therapy to guide TA-CE manipulation and assess its efficacy, thus to investigate C arm CT imaging method and assess its application range. Results In TACE therapy for HCC patients, using diluted non-ionic contrast agent in C arm CT imaging and taking arterial images in unenhanced phase, early phase and parenchymal phase can meet the needs of detecting carcinoma and displaying feeding artery, abnormal feeding artery and abnormal travelling artery. Therefore, we can assess survived carcinoma, lipiodol deposition conveniently, accurately and comprehensively as well as whether the feeding artery is embolized completely to evaluate the efficacy of TACE therapy. Carm CT scan didn?t significantly increase x-ray radiation dose, and mean operation time was prolonged by 9?5 minutes. Conclusion C arm CT is expected to be used safely and effectively. C arm CT imaging applied in TACE therapy for HCC patients will facilitate the design of therapeutic regimen before intervention, guiding of manipulation during intervention and immediate assessment after intervention.
