摘　　要：目的CT冠状动脉成像(CTA)与数字减影脑血管造影(DSA)检查诊断冠状动脉狭窄的价值评估。方法选取本院影像中心2019年9月—2022年9月44例临床拟诊冠状动脉狭窄患者,先后进行CTA及DSA造影检查,视DSA检查结果为“金标准”,对比分析两种方法检查结果。结果CTA诊断阳性38例(含假阳性2例)、阴性6例(含假阴性1例),敏感度95.00%、特异度85.71%、准确度93.62%,Kappa=0.762,代表度为高度。结论CTA诊断冠状动脉狭窄的结果准确可靠,与DSA检查相似,可广泛应用于冠状动脉狭窄的临床初步诊断。Objective To evaluate value of CT coronary angiography(CTA)and DSA angiography in diagnosing coronary artery stenosis.Methods The paper chose 44 clinically suspected patients with coronary artery stenosis in imaging center of our hospital from September 2019 to September 2022,treated with CTA and DSA imaging examinations successively,and compared and analyzed results of two methods"gold standard"of the DSA examination.Results CTA diagnosis was positive in 38 cases(including 2 false positives)and negative in 6 cases(including 1 false negative),with sensitivity of 95.00%,specificity of 85.71%,and accuracy of 93.62%.Kappa=0.762,which indicated high representativeness.Conclusion CTA diagnosis is accurate and reliable for coronary artery stenosis,which similar to DSA examination,and can be widely used in clinical preliminary diagnosis of coronary artery stenosis.
