摘　　要：目的探讨多层螺旋CT血管造影(MSCTA)及三维重建对上腹部肿瘤介入治疗的指导价值。方法对27例上腹部肿瘤患者介入治疗前后分别行MSCTA检查,并应用最大密度投影(MIP)、容积再现技术(VRT)对血管进行三维重建。结果27例患者共进行MSCTA检查及三维重建42次。共发现腹腔供血动脉解剖变异5例,栓塞治疗后肿瘤侧支动脉形成7支,腹腔动脉走行异常2例。MSCTA显示腹腔动脉及其分支的三维结构、介入栓塞治疗后有无侧支血管的形成及来源优于DSA。结论MSCTA检查及三维重建,能直观、清晰地显示肿瘤的供血血管立体解剖图像,对制定手术方案具有重要指导意义。Objective To assess the usefulness of the MSCTA with 3D reconstruction to epigastric tumors in interventional treatment. Methods MSCTA were performed in 27 cases of cpigastric tumors before and after interventional treatment. 3D reconstruction were taken for blood vessels with technique of MIP （maximum intensity projection）and VRT （volume rendering technique）. Results 42 times MSCTA and 3D reconstruction were performed in 27 cases of epigastric tumors. We discovered 5 feeding arteries with mutation in abdominal cavity, 7 collateral branches formed after embolization and 2 abnormal courser of celiac artery. The display of vasculative with MSCTA was better than that of DSA. Conclusion 3D-MSCTA for cpigastric tumors not only can show directly and clearly the stereo-anotomic images of the tumor feeding vessels but also provide guidance for planning the treatment. （J Intervent Radiol, 2007, 16： 375-377）
