64层螺旋CT诊断不同程度冠状动脉狭窄的临床价值

【摘要】 目的用传统的冠状动脉造影作对照,评价64层螺旋CT诊断冠状动脉不同程度狭窄的准确性。方法 116例患者临床怀疑冠状动脉粥样硬化性心脏病并同期接受64层螺旋CT冠状动脉造影及常规冠状动脉造影,计算冠状动脉不同程度狭窄的敏感性、特异性、准确性、阳性预测值、阴性预测值。结果 64层螺旋CT诊断可评估冠状动脉中度、重度及轻度狭窄的敏感性为95.73%、89.7%、70.0%,特异性为98.7%、95.7%、88.1%,准确性为98.7%、95.7%、88.1%,阳性预测值为83.0%、80.7%、36.3%,阴性预测值为99.7%、97.9%、96.8%。结论 64层螺旋CT是一种有效的无创性的检测冠状动脉狭窄的工具。更多还原

【Abstract】 Objective To evaluate the accuracy of 64-slice spiral computed tomography in detection varying degrees coronary artery stenosis comparing with the results of conventional coronary angiography.Methods 116 patients suspected coronary heart disease had underwent both 64-slice spiral CT and conventional coronary angiography.The sensitivity specificity accuracy positive predicted value and negative predicted value of the CT coronary angiography in detection varying degrees coronary artery stenosis were calculated.Results The sensitivity of 64-slice spiral CT in detection of moderate severe and mild coronary artery stenosis is 95.73%,89.7%,70.0%;The specificity is 98.7%,95.7%,88.1%.The accuracy is 98.7%,95.7%,88.1%.The positive predicted value is 83.0%,80.7%,36.3%.The negative predicted value is 99.7%,97.9%,96.8%.Conclusion 64-slice spiral CT is a useful and non-invasive tool for detecting coronary artery stenosis.更多还原
