目的探讨多层螺旋CT灌注扫描在肾脏血流灌注中的应用及对比剂注射流率对灌注参数的影响。
Objective To evaluate the application of multi-slice spiral ct perfusion imaging in the kidney and the influence of various injection rate on perfusion parameters.
结论多层螺旋CT可对肾脏组织血流灌注进行定量分析，但注射流率影响灌注数值。
Conclusion Multi-slice spiral ct can provide quantitative analysis to renal blood perfusion, but injection flow rate influence the perfusion parameters.
结论肌钙蛋白升高的非ST段抬高型急性冠状动脉综合征患者冠状动脉造影特点为血栓发生率高、狭窄较重、血管闭塞率高、血流较慢、心肌组织灌注不良者多。
Conclusions The angiographic features in patients with NSTE-ACS are of higher incidence of thrombus, tighter percent stenoses, higher rate of vesse1 occlusion and closed microvasculature.
