16层螺旋ct冠状动脉血管造影临床应用探讨
, PP. 218-222
Keywords: 体层摄影术,x线计算机/方法,冠状动脉疾病/诊断,冠状血管造影术
Abstract:
目的探讨多层螺旋ct冠脉造影(multislicespiralctcoronaryangiography,msctca)的成像技术及其临床应用价值。方法对79例对象行msctca检查,利用多种重建方法进行重建,分析影响冠脉成像质量的重要因素,msct对冠脉的显示能力,冠脉斑块性质及钙化程度,评价管腔狭窄及其程度,并对桥血管和支架的显示及通畅性进行评价。结果左冠脉主干及前降支重建的最佳时相为75%r-r时相,左回旋支及右冠脉为62.5%r-r时相。以75%的相位窗重建得到容积再现的图像为最佳。msctca对冠脉1~3级分支、甚至部分4级分支显示清晰,对冠脉斑块显示良好,对冠脉狭窄显示较佳,对搭桥血管及内支架显示良好。结论16层msctca可作为冠心病的筛选手段及在血运重建术后复查中有很高的临床应用价值。
