     [摘要] 目的：评价16层螺旋CT冠状动脉成像(multislicespiral CT coronary angiography，MSCTCA)对冠状动脉狭窄的诊断价值。方法：对46例患者行心电门控16层螺旋CT冠状动脉造影，与选择性冠状动脉造影(selective coronary angiography,SCA)对照,评价MSCTCA诊断冠状动脉50%以上狭窄的准确性。结果：46例MSCTCA图像与相应SCA比较，MSCTCA诊断冠状动脉50%以上狭窄的敏感度、特异度、准确度、阳性预测值和阴性预测值分别为82.22%、95.68%、92.39%、86.05%和94.33%。结论：16层螺旋CT冠状动脉造影是一种无创、简便、安全的冠状动脉成像方法，对冠状动脉狭窄50%以上的患者有较高的诊断价值。

    Abstract：Objective To evaluate the clinical value of 16slices spiral CT coronary angiography in the detection of coronary artery stenosis.Methods 46 patients were detected with ECGgated MSCT.And all patients were also investigated with SCA.Results of the determination of≥50% stenoses of the vessel diameter with MSCT were compared to findings of SCA.Results The sensitivity,specificity,accuracy,positive and negative prediction value of MSCTCA were 82.22%、95.68%、92.39%、86.05% and 94.33%,respectively.Conclusion 16slice spiral CT coronary angiography is a noninvasive,simple and safe method.16slice spiral CT coronary angiography has a good clinical value in the diagnosing of ≥50% stenoses of the vessel diameter. ......
