| 目的 评价多层螺旋CT(MSCT)诊断冠状动脉狭窄的可行性和准确性。方法 35例临床拟诊冠心病患者行冠状动脉MSCT成像,同时接受选择性冠状动脉造影。分析MSCT图像质量,并与选择性冠状动脉造影相比较。结果 以冠状动脉造影结果作为金标准,MSCT诊断狭窄≥50%的敏感度、特异度、阳性预测值、阴性预测值分别为79.4%、95.7%、83.1%、94.6%。结论 MSCT能较准确诊断冠状动脉50%以上的狭窄,是无创性诊断冠状动脉狭窄的重要工具。 |

| Objective To evaluate the feasibility and accuracy of multi-slice spiral CT (MSCT) in the detection of coronary artery stenosis. Methods Thirty-five patients with suspected coronary artery diseases underwent contrast-enhanced MSCT and conventional selective coronary angiography, the outcomes of the two kinds of examination were compared. Results Taking conventional selective coronary angiography as the gold standard, the sensitivity, specificity, and positive and negative prediction values in detecting ≥50% stenotic lesions for assessable segments was 79.4%, 95.7%, 83.1%, and 94.6%, respectively. Conclusion MSCT is capable of achieving high accuracy in detecting coronary artery stenosis, and is a reliable technique in diagnosing coronary artery disease. |
