摘　　要：目的探讨双源CT诊断不同程度冠状动脉狭窄的临床价值。方法选取来我院因临床拟诊冠心病而接受双源CT和传统冠状动脉造影检查的患者36例。结果双源CT检查结果与冠状动脉造影检查结果相比,其冠状动脉狭窄诊断的敏感度为94.7%、诊断特异性为95.5%、阳性预测值为83.4%、阴性预测值为98.78%,诊断准确率为95.3%。双源CT检查对重度狭窄诊断敏感度低于轻度狭窄和中度狭窄的诊断敏感度,比较差异具有统计学意义(P<0.05)。结论与传统冠状动脉狭窄诊断方式冠状动脉造影相比,双源CT扫描具有扫描迅速、诊断准确率较高,无创伤等临床优势。Objective To investigate the clinical value of dual source CT in the diagnosis of coronary artery stenosis.MethodsThirty-six patients with clinicaly suspected coronary heart disease in our hospital received with dual source CT and conventional coronary angiography.Results Dual source CT findings and coronary angiography results were compared and the diagnosis of coronary artery stenosis sensitivity for 94.7%,specificity of diagnosis of 95.5%,the positive predictive value for 83.4%,the negative predictive value was 98.78%. The diagnostic accuracy rate was 95.3%. Dual source CT in the diagnosis of severe stenosis diagnostic sensitivity was significantly lower than that of mild stenosis,moderate stenosis diagnosis sensitivity, he difference had statistical significance（P〈 0.05）.Conclusion With the traditional coronary artery stenosis diagnosis coronary angiography were compared with and dual source CT scan with rapid scanning,high accuracy in the diagnosis and noninvasive clinical advantage.
