7、断治疗中的应用方法：1选取2014年1月～2014年12月我院共进行肝癌灌注化疗栓塞627例次，包括原发性肝癌442例次，转移性肝癌185例次，其中应用锥形束CT扫描97例次，其中观察病灶9例次，观察供血动脉17例次，观察栓塞效果41例次。2病例分组2.1对9例次常规DSA造影时显示病灶不明显或者发现额外病灶（螺旋CT未发现的病灶）的患者，行锥形束CT增强扫描，比较二者发现病灶数量。2.2对17例次常规DSA造影时发现血管走形迂曲或重叠的患者，行锥形束CT增强扫描，观察肿瘤供血动脉走形，指导插管。2.3在41例次乏

8、血供病人栓塞后，普通DSA显示栓塞效果不佳，行锥形束CT平扫观察病灶是否栓塞完全。3锥形束CT扫描方法由术者根据病情需要决定是否对患者行锥形束CT检查。告知患者锥形束CT检查全过程，并对患者进行呼吸训练，嘱咐患者身体尽量保持不动并屏气。中心线置于肝脏中心，范围包括全部肝脏，扫描模式采用DynaCT8SDR模式。观察病灶锥形束CT扫描：使用DynaCT8SDR
