摘　　要：目的:探讨64排螺旋CT冠脉成像对冠心病的诊断价值。方法:以冠脉造影(CAG)结果为金指标,采用64排螺旋CT对100例疑诊冠心病患者的冠脉主干及主要分支400节段进行重建和分析,评价其诊断冠心病的灵敏性和特异性。结果:64排螺旋CT能清晰显示冠脉主干及分支狭窄、钙化、开口起源异常及桥血管病变,对冠脉狭窄性病变的诊断准确性高,诊断冠脉病变的灵敏度96.37%,特异度96.14%,阳性预测值95.88%,阴性预测值96.6%。但对慢性闭塞性病变诊断性的准确率稍差,灵敏度50%,特异度96.77%,阳性预测值62.5%,阴性预测值94.73%。结论:64排螺旋CT冠脉成像对冠脉狭窄病变、桥血管、心肌桥、支架管腔均显影良好,对钙化病变诊断率优于冠脉造影,可以作为冠心病高危人群无创性筛选检查及冠脉支架、搭桥术后随访手段。Objective： To evaluate the clinical value of 64-slice spiral CT angiography on diagnosis for coronary artery disease （CAD）. Methods： To select 100 CAD patients performed 64-slice spiral CT angiography, and contrast analyze the results of 64-slice spiral CT angiography and coronary angiography. Results： Compared with coronary angiography regard as golden standard, the diagnosis sensitivity was 96.37%, specificity 96. 14%, positive predictive value 95.88%, and negative predictive value 96.6% for 64-slice spiral CT angiography. Conclusion： As the non-intervention diagnosis method in coronary artery disease, the 64-slice spiral CT angiography is credible and should be popularized.
