【摘要】 目的:探讨320排螺旋CT冠状动脉成像对冠心病诊断的临床应用价值。方法:85例病人先后进行320排螺旋CT冠状动脉成像(SCTCA)和选择性冠状动脉造影(CAG)。以CAG为诊断冠心病(CHD)的"金标准",比较320排螺旋CT检出CHD的敏感度,特异度,阳性预测值,阴性预测值和准确度。结果:320排螺旋CT诊断CHD的敏感性,特异性,阳性预测值,阴性预测值,准确度分别是:95.65%(44/46)、74.36%(29/39)、81.48%(44/54)、93.55%(29/31)、85.9%(73/85)。结论:320排螺旋CT冠状动脉成像是一种简单易行、安全可靠的无创性检查,可作为冠心病的筛选及术后复查的方法。更多还原

【Abstract】 Objective: To study clinical application value of 320-slice spiral computed tomography(SCTCA) for diagnosing coronary artery disease.Methods: A total of 85 patients underwent 320-slice spiral CT and selective coronary angiography(CAG).With CAG as gold standard diagnosing coronary heart disease(CHD),sensitivity,specificity,positive predictive value,negative predictive value and accuracy were compared between 320-SCTCA and CAG.Results: Sensitivity was 95.65%,specificity was 74.36%,positive predictive value was 81.48%,negative predictive value was 93.55% and accuracy was 85.9% diagnosing coronary artery disease by 320-slice spiral CT.Conclusion: 320-slice spiral computed tomography is a simple,safe,reliable non-invasive measurement,may be used for screening coronary heart disease and reviewing after operation.更多还原
