64层螺旋CT血管成像与冠状动脉造影对冠心病诊断价值的对比研究
Chinese Journal of Geriatric Heart Brain and Vessel Diseases(2007)
Abstract
目的 评价64层螺旋CT在冠状动脉造影方面的诊断价值.方法 58例临床诊断或可疑冠心病患者行64层螺旋CT冠状动脉成像检查,分别对左主干、左前降支、回旋支和右冠状动脉及其分支的重建图像行影像学评价,所有患者均行常规选择性冠状动脉造影检查作为对照.结果 58例患者共757(87.0%)节段的冠状动脉(血管直径≥1.5 mm)成像,638节段(84.3%)可用于多层螺旋CT和冠状动脉造影定量分析.冠状动脉造影共发现狭窄101节段,多层螺旋CT发现狭窄104节段,多层螺旋CT对冠状动脉狭窄诊断的敏感性为86.1%,特异性为96.8%.结论 64层螺旋CT冠状动脉造影可作为诊断冠状动脉病变的一种无创筛选方法.
