摘要
目的 探究64层螺旋CT诊断不同程度冠状动脉狭窄的临床价值.方法 选取2014年10月-2015年9月收治的疑似冠心病的患者68例,所有患者均进行64层螺旋CT及常规冠状动脉造影检查.观察两种检查方法结果的一致性及64层螺旋CT诊断不同程度冠状动脉狭窄的准确率、敏感度合特异性.结果 64层螺旋CT正确诊断冠状动脉狭窄62例,错误诊断6例,与常规冠状动脉造影结果进行Kappa检验后,一致性较高(k=0.79,P＜0.05);轻度的准确率为98.53％、敏感性为96.88％、特异性为100％;中度的准确率为95.59％、敏感性为81.81％、特异性为96.49％;重度的准确率为92.65％、敏感性为82.35％、特异性为96.08％;闭塞的准确率为95.59％、敏感性为100％、特异性为95％.结论 64层螺旋CT诊断不同程度冠状动脉狭窄的准确率、敏感性和特异性均比较高,值得推广应用.
Abstract
Objective To explore the clinical value of 64 slice spiral CT in the diagnosis of coronary artery stenosis.Methods Totally 68 cases were selected from October 2014-2015 year in September in our hospital with suspected coronary heart disease,All patients underwent 64 slice spiral CT and conventional coronary angiography.The consistency of results of two methods and 64 slice spiral CT in the diagnosis of different degrees of accuracy,coronary artery stenosis and sensitivity specificity.Results 64 slice spiral CT diagnosis of coronary artery stenosis in 62 cases,The wrong diagnosis of 6 cases.Kappa test and conventional coronary angiography results,A high consistency (k =0.79,P ＜ 0.05);The accuracy rate of mild was 98.53％,sensitivity was 96.88％,specificity was 100％;The accuracy rate of moderate was 95.59％,the sensitivity was 81.81％,specificity was 96.49％;The accuracy rate was 92.65％,with a sensitivity of 82.35％,specificity of 96.08％;The accuracy rate of occlusion was 95.59％,the sensitivity was 100％,specificity was 95％.Conclusion 64 slice spiral CT in the diagnosis of different degrees of accuracy,coronary artery stenosis,the sensitivity and specificity were relatively high,it is worthy of popularization and application.
