摘　　要：目的 探讨16层螺旋CT冠状动脉血管成像在冠状动脉狭窄中的临床应用价值.方法 对54例接受过16层螺旋CT冠状动脉血管成像和常规冠状动脉造影（CAG）的患者进行回顾性分析,将16层螺旋CT发现病变的患者冠脉图像作为阳性结果,没有发现病变的作为阴性结果,以冠脉造影结果作为冠心病诊断的＂金标准＂.通过对比研究,判断16层螺旋CT冠脉成像对冠脉狭窄诊断的敏感性和特异性.结果 16层螺旋CT冠状动脉血管成像对冠心病诊断的敏感性为89.8%,特异性为93.6%.结论 16层螺旋CT冠脉血管成像技术是一种无创、简便的检查方法,对冠状动脉狭窄的显示具有较高的准确性.作为一项非创伤性技术,它是评价冠状动脉狭窄病变的重要筛选手段.Objective To evaluate the clinical application value of 16 - slice spiral CT coronary angiography. Methods 54 patients undergoing both 16 - slice spiral CT and conventional coronary artery angiography were included in this retrospective study. Those patients being found coronary lesions by 16 -slice spiral CT were seen as positive results, those has not found disease were seen as negative results. Convention- al coronary artery angiography was seen as the gold standard for diagnosis of coronary heart disease, by the comparative study, sensitivity and spe- cificity of 16 - slice spiral CT coronary image were determined on the diagnosis of coronary stenosis. Results The sensitivity of 16 - slice spiral CT coronary image was 89.8% ,specificity was 93.6% to the diagnosis of coronary disease. Concluson 16 - slice spiral CT coronary angiogra- phy technology is the accurate, non - invasive detection of significant coronary stenosis. It provides a good visualization. It is valuable in demon- strating lumen stenosis. It should be used as reliable exam of coronary heart disease in elinial practice.
