1、64层螺旋Ct检测冠状动脉狭窄的探讨64层螺旋CT检测冠状动脉狭窄的探讨【摘要】目的探讨64层螺旋CT在诊断老年及中青年冠状动脉狭窄的敏感性等指标的差异。方法对203例经冠状动脉造影证明为冠脉狭窄患者的临床病例资料进行分析。结果老年患者轻、中、重度冠脉狭窄的敏感性分别为78.3%.79.2%、90.6%;中青年患者之敏感性分别为91.8%、86.7%、91.7%。结论64层螺旋Cr诊断老年冠脉狭窄的敏感性低于中青年，佬、中度狭窄时差异有统计学意义,重度狭窄时敏感性无统计学差异。【关键词】64层螺旋CT;老年；中青年；冠状动脉狭窄ContrastStudyof64-siiceSpiralCTDe
