摘　　要：目的:评价64排多层螺旋CT在冠脉临界病变诊断和冠脉斑块性质判断方面的临床应用价值。方法:2005年8月至2008年5月期间共选择72例患者的189个冠脉节段,将其CT影像与血管内超声(IVUS)逐一进行对比分析。结果:以IVUS为金标准,64排螺旋CT诊断冠状动脉临界病变总的敏感性为95%、特异性为96%、准确度为97%;在冠脉斑块性质的判断方面,对于脂质斑块的敏感性为72%、特异性为86%,对于纤维斑块的敏感性为76%、特异性为93%,对于钙化斑块的敏感性为95%、特异性为98%。结论:64排多层螺旋CT做为无创筛查手段,在冠脉临界病变诊断和冠脉斑块性质判断方面结果可靠,应予推广。Objective： To evaluate the clinical value of 64 MSCT in diagnose for borderline lesion and plaque characteristic,include lipid plaque, fibrotic plaque and calcific plaque. Methods：To select 185 vessel segments form Aug 2005 to May 2008,and contrast analyse the results of 64 MSCT and IVUS. Results： As well as IVUS is the golden standard, the sensitivity for determining borderling les^on was 95%, specificity 96%, accuracy 97%,and the sensitivity for lipid plaque was 72%, specificity 86%, for fibrotic plaque was 76%, specificity 93%, for calcific plaque was 95%, specificity 98%. Conclusions：As the non--intervention diagnose method in determining borderline lesion and different characteristic plaque, the results of 64 MSCT was credible and should be popularized.
