CT血管造影在肾上腺恶性肿瘤介入治疗中的应用价值

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。

Evaluation of CT Angiography in the Interventional Treatment of Malignant Adrenal Tumors

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.
