摘要
目的探讨多层螺旋CT血管造影(MSCTA)及三维重建对肾上腺肿瘤介入治疗的指导价值。方法对5例肾上腺皮质癌患者,在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)对肿瘤血管进行三维重建。结果5例患者共进行MSCTA检查及三维重建7次,共发现肿瘤血管及侧支血管21支。MSCTA在显示肿瘤血管及其解剖关系方面优于数字减影血管造影(DSA)。结论MSCTA检查及三维重建,能全面、清晰地显示肾上腺肿瘤的供血血管的起源、数量,对制定手术方案具有重要指导意义。
Objective To evaluate the usefulness of the MSCTA with 3D reconstruction to adrenal tumors in interventional treatment. Methods MSCTA were performed in 5 patients with malignant adrenal 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 7 times of MSCTA and 3D reconstruction were performed in 5 patients. 21 feeding arteries and collateral branches were discovered. The display of tumor feeding vessels and its anatomy relation with MSCTA were better than that of DSA. Conclusion 3D-MSCTA for adrenal tumors not only can show the numbers and origins of tumor feeding vessels clearly but also provide guidance for planning the treatment.
