摘　　要：目的分析16层螺旋CT冠状动脉成像技术在临床冠心病诊断中的应用价值。方法选用合理的设备参数设置，通过对60例患者进行16排CT心脏快速扫描，利用图像后处理技术，对冠状动脉进行三维立体重建，对冠状动脉图像进行观察，以显示出冠状动脉病变部位等情况，并与常规造影对照。结果在60例患者的658个节段（血管直径≥2mm）中，CT图像能满足诊断需要的有559节段（87％）。对于通过CT图像可以满足诊断需求的冠状动脉阶段，其中显示的中度或中度以上狭窄的特异度与敏感度分别为95％和86％。若将不能满足诊断要求的99个节段计算在内，则显示中度或中度以上狭窄的敏感度为77．7％。结论CT冠状动脉成像技术有较高的临床应用价值，可用于无创性筛选和诊断冠心病。Objective To investigate the application value of 16-slice spiral CT coronary angiography for clinic coronary artery heart disease treatment. Methods We selected a reasonable set of equipment parameters. 60 cases underwent a 16-slice CT cardiac quick scan. Then we reconstructed three-dimensional coronary artery with image post-processing techniques, and observed the coronary artery images to show the location of coronary artery disease, etc. The results were compared with coronary artery angiography. Results In the 658 coronary artery segments （vessel diameter≥ 2 ram）of 60 patients, 559 were judged to be evauable by CT （87%）.The scnsitivity and the specificity for the detection of stenosis ≥ 50% were 87.5% and 96.5% respectively. When 99 coronary artery segments judged to be unevaluablem were included in the analysis, the sensitivity was 77.7%. Conclusion Coronary angiography of 16-slice spiral CT has high clinical value, it could be used for noninvasive screening and diagnosis for coronary artery heart disease.
