摘　　要：目的:探讨320排螺旋CT冠状动脉成像(MSCTA)在诊断无症状冠心病中的应用价值。方法:对60例无症状冠心病受检者行MSCTA检查后,以冠状动脉造影(CAG)为对照,对比分析其诊断冠状动脉狭窄的敏感性、特异性和准确性。结果:依节段计算MSCTA准确性,其灵敏度、特异度分别为91.28%、93.78%。结论:MSCTA判断冠状动脉中重度狭窄具有较高准确性,是一种无创、可靠、有效的冠状动脉检查方法,可作为无症状人群冠状动脉狭窄筛查的非创伤性方法。Objective：To evaluate the application of 320 row spiral CT coronary angiography in the diagnosis of a- symptomatic coronary artery diseases. Methods： A total of 60 asymptomatic subjects with suspected coronary artery disease were examined by MSCT. The sensitivity, specificity and accuracy of MSCTA were calculated compared with CAG. Results： At segment level,the sensitivity was 91.28% and the specificity 93. 78%. Conclusion： MSCT coronary angiography has a high accuracy rate for detection of coronary stenosis. It is a noninvasive,reliable and effective method for diagnosing artery disease,and also can be used in the screening of coronarv artery stenoses for asymptomatic patients.
