摘　　要：目的:研究128层螺旋CT在透析患者上肢CT血管成像中的临床应用价值。方法:回顾性分析30例患者的64层CT图像(64层组)与39例患者128层CT图像(128层组),对扫描数据进行三维重建后比较两组患者的动脉分支级别、血管边缘、静脉干扰评分及瘘口显示情况的差异。结果:128层组前臂与手部动脉分支级别显示评分高于64层组,差异有统计学意义(P<0.05);128层组肩部、上臂及前臂的血管边缘光滑度显示评分高于64层组,差异有统计学意义(P<0.05)。结论:128层螺旋CT在透析患者上肢血管成像中血管、内瘘口以及流入流出道等细节方面显示效果更理想。Objective：To study the clinical application value of 128 layers spiral CT in upper limbs CT angiography of dialysis patients. Methods： Retrospective analysis was used to compare the 64 layers spiral CT angiography （group 64 layers, 30 cases） and 128 layers spiral CT angiography （group 128 layers, 39 cases）. The branch level, vessel edge, venous interference score and display oforificium fistulae after 3D reconstruction of scanning data were compared. Results： The scores for the display of forearm and hand arterial branch level of group 128 layers were higher than those in group 64 layers, the differences were statistically significant （P〈0.05）. The scores of the display of shoulder , upper arm and forearm vessel edge of group 128 layers were higher than in group 64 layers, the differences were statistically significant （P〈0.05）. Conclusions： 128 layers spiral CT was more ideal in displaying the details such as certain blood vessels, fistula and intoflow and outflow in the upper limbs vascular imaging in dialysis patients.
