| 摘 要： | 目的 探讨多层螺旋CT(MSCT)灌注成像对肾透明细胞癌血流灌注的定量诊断价值.方法 回顾性分析经手术病理证实的肾透明细胞癌58例MSCT灌注扫描数据,使用256彩色直观显示癌组织及对侧正常肾组织血流灌注图,分别计算出肿瘤生长活跃部分及对侧正常肾皮质血流量(BF)、血容量(BV)、对比剂平均通过时间(MTT)及毛细血管表面通透系数(PS),并进行对比分析、定量研究.结果 肿瘤生长活跃部分的BF、BV、MTT、PS与对侧肾皮质各灌注参数间均有显著差异(P<0.01).结论 MSCT灌注成像能定量评价肾透明细胞癌的血流动力学变化,同时反映肿瘤的形态和功能,并能判断预后.

| Abstract: | Objective To approach quantitative diagnostic value of MSCT perfusion imaging in blood perfusion of suprarenal epithelioma.Methods 58 cases of MSCT perfusion imaging data of suprarenal epithelioma proved by operation were analyzed and blood perfusion imaging both cancer and normal nephridial tissue opposite side were demonstrated.Blood flow(BF),blood volume(BV),mean transit time(MTT) and permeability coefficient(PS) both in active part of tumor and normal nephridial tissue opposite side were calculated.Resu... |
