目的探讨64层螺旋CT冠状动脉成像技术对诊断冠心病的临床价值.方法选取本院2006年接受64层螺旋CT冠状动脉成像检查,并在1个月内接受选择性冠状动脉造影检查的113例患者,将CT检杳结果与冠状动脉造影结果进行比较分析.结果共计收集113例患者的可评价节段910个.64层螺旋CT诊断冠心病的灵敏度为73.8%,特异度为97.0%,一致率93.2%,阳性预测值为82.7%,阴性预测值为95.0%,阳性似然比24.4.结论 64层螺旋CT冠状动脉成像具有较高的特异度、阴性预测值、阳性似然比,用于诊断冠心病有较高的准确性.

Objecfive To explore clinical value of 64-slice spiral CT coronary angiography in diagnosing coronary atherosclerotic heart disease. as compared to that with selective coronary angiography.Methods One hundred and thirteen patients who underwent both 64-slice spiral CT coronary angiography as well as selective coronary angiography at an interval of no more than one month at Zhongshan Hospital.Shanghm in 2006 were selected for the study and their imaging reports were analyzed and compared.Results Images of 910 segments of coronary arteries were collected and assessed.Sensitivity,specificity and likelihood ratio for negative test result of 64-slice spiral CT coronary angiography in diagnosis of coronary atherosclerotic heart disease were 73.8 percent.97.0 percent and 24.4,respectively,with an overall agreement of 93.2 percent,positive predictive value of 82.7 percent and negative predictive value of 95.0 percenL Conclusions Sixty-four-slice spiral CT coronary angiography has hish specificity,negative predictive value and positive likelihood ratio,with high accuracy,in diagnosing coronary atherosclemtic heart disease.
