摘　　要：目的探讨宝石能谱CT低剂量辐射技术对冠状动脉成像的价值。方法回顾性分析80例宝石能谱CT对冠状动脉成像及同时进行冠状动脉造影患者的影像学资料,通过分析宝石能谱CT的冠状动脉成像的图像质量,与冠状动脉造影进行对比,评价宝石能谱CT冠状动脉成像的准确性。结果宝石能谱CT的冠状动脉成像图像质量良好,显示近端及远端分支非常清晰;宝石能谱CT对冠状动脉成像的敏感性为97.6%,特异性为96.6%,阳性预测值为96.8%,阴性预测值为96.1%。结论宝石能谱CT对冠状动脉成像图像质量高且具有较高的诊断准确性。Objective To explore the value of low-dose gemstone spectral imaging for coronary angiography. Methods Imaging data of 80 patients who underwent gemstone spectral imaging CT and coronary angiography were retrospectively analyzed. The accuracy of gemstone spectral ima- ging was assessed through analyzing the image quality and comparing with coronary angiography. Results Gemstone spectral imaging had good image quality and clearly showed proximal and dis- tal branches. The sensitivity and specificity of gemstone spectral imaging were 97. 6% and 96.6% ,respectively. The positive predictive value and negative predictive value were 96.8% and 96.1%,respectively. Conclusion Gemstone spectral imaging can produce high quality images and had high accuracy in the diagnosis of coronary heart disease.
