摘　　要：目的探讨肝癌介入治疗后CT平扫、双期增强及3DCT对肝癌肝动脉插管化疗及碘油栓塞治疗(LP-TACE)术后的随访价值。方法43例肝癌LP-TACE治疗后行CT平扫及双期增强扫描,10例同时行MIP、曲面重建。结果43例肝癌LP-TACE治疗后碘油沉积形态分4个类型:完全型、缺损型、簇集型和稀少型。35例LP-TACE治疗后肿瘤内见非坏死低密度区,增强后18例动脉门静脉双重供血型,10例动脉供血型,4例门静脉供血型,3例少血供型。10例肝动脉及门静脉血管MIP、曲面重建可显示肝动脉及门静脉与非坏死低密度区的关系。结论CT三期扫描及三维重建是显示肝癌LP-TACE治疗后残留病灶、反映其血供变化的有效方法,对制订新的治疗方案有指导意义。Objective To evaluate the effectiveness of hepatic arterial chembolization using lipodol（LP-TACE） on primary hepatic carcinomas（HCC） by plain, dual-phase CT scanning and three dimensional CT（3DCT）. Methods Forty-three patients with HCC after LP-TACE were examined with plain scanning and dual-phase CT. 3DCT model of the maximum intensity projection （MIP） , the curved planner reconstructions were simulaneously done for 10 cases. Results Lipiodol deposition shapes of 43 cases with HCC after LP-TACE were divided into four types： completely, defect, clump and paueiform types. 35 cases with HCC after LP-TACE showed viable tumor areas. Enhanced tumor vessel or tissues in viable tumor areas were found during hepatic dual-phase in 18 cases, during hepatic artery-phase only in 10 and hepatic portal vein-phase only in 4. The value tumor area unenhaneed during hepatic dual-phase was found in 3 cases. In 10 cases, the relation between the viable tumor area and branches of hepatic artery and portal vein was showed with MIP and curved planner reconstruction. Conclusion CT tri-phase scan and 3DCT is effective in showing refiquus focus and reflecting the blood supply of the viable tumor area. It has guidance significance for working out the new treatment plan.
