摘　　要：目的评价64层CT冠状动脉成像(SCTCA)对冠状动脉临界病变狭窄程度和斑块性质判断的准确度。方法 50例拟诊或确诊冠心病患者分别行64层SCTCA和血管内超声(IVUS),并以IVUS结果作为标准进行对比分析。结果 64层SCTCA诊断冠状动脉临界狭窄的敏感性、特异性、准确性分别为88.9%、96.6%、94.8%;准确检出了28处脂质斑块中的23处、15处纤维斑块中的12处及11处钙化性斑块中的10处。结论 64层SCTCA评估冠状动脉临界病变具有较高的准确性,值得推广。Objective To evaluate the judgement accuracy of 64-slice spiral computed tomography coronary angiography（SCTCA） on intermediate coronary stenosis and plaque characteristic.Methods Totally 50 patients suspected or confirmed coronary and heart disease were examined by 64-slice SCTCA and intravascular ultrasound（IVUS）,and then we did contrast analysis based on the results of IVUS which was regarded as a standard.Results The diagnostic sensitivity,specificity,and accuracy of 64-slice SCTCA in detecting intermediate coronary stenosis were 88.9%,96.6% and 94.8% respectively.64-slice SCTCA enabled a correct detection of plaque with 23 out of 28 sections containing soft plaques,12 out of 15 sections containing mixed plaques,and 10 out of 11sections containing calcified plaques.Conclusion The accuracy of detecting intermediate lesion of the coronary arteries with 64-slice SCTCA is high and it should be popularized.
