1、CT冠脉成像对心肌桥的诊断及其意义【摘要】目的:评价64排CT冠脉成像(CTA)对心肌桥的诊断及其意义。方法:选择100例有冠心病症状或是心脏体检的患者,为其做64排CTA,从中选择出有心肌桥表现的病例,然后对其进行分析总结,并对临床有冠心病症状患者做冠脉造影来对比观察。结果:100例病例中CTA发现心肌桥18例,而冠脉造影只发现2例。结论:本组病例中CTA对心肌桥的检出率为18%,冠脉造影检出率为2.5%,所以CTA对心肌桥的检出率明显高于冠脉造影。64排CT冠脉成像可以清晰而且直观地显示冠状动脉及其细小分支,并精确显示血管的走行情况、管壁的粥样斑块及钙化、血管的狭
2、窄程度等,与目前诊断冠脉的金标准冠脉造影相比,本检查方法不但对心肌桥的检出率明显高于前者,而且为无创性检查、费用低廉,所以64排CT冠脉成像还可以作为体检手段或为冠脉造影做筛查。【关键词】64排CT;冠脉成像;碘帕醇;心肌桥;无创性AbstractObjective:ToappraisethesignificanceofBrillianceCT64coronaryarteryimageformation(CTA)inthediagnosisofthecoronarymyocardialbridge.Methods:100patientswithcoronarydise
