目的：比较冠状动脉CT血管成像（CTA）与血管内超声（IVUS）诊断冠状动脉钙化病变的效果。方法：选择经我院临床诊断为冠心病或疑似冠心病患者50例为研究对象，所有患者均行冠状动脉CTA、IVUS检查，观察冠状动脉斑块特征、不同类型斑块CT值，以血管内超声为对照，评估冠状动脉CTA诊断效果。结果：两种检测方法在斑块面积、斑块负荷、管腔面积方面比较差异无统计学意义；钙化斑块CT值明显高于纤维斑块和脂质斑块[（725.68±68.42）Hu比（58.12±7.05）Hu、（60.21±6.78）Hu ，P均＜0.01]；冠状动脉CTA诊断钙化斑块灵敏度、特异性、准确性、阳性预测值、阴性预测值分别为92.86％、92.86％、92.86％、81.25％、97.50％。结论：冠状动脉CT血管成像在冠状动脉钙化病变定性定量检测中，具有较高的诊断效果，可以作为筛查的首选方法。

Objective:To compare diagnostic effect between coronary CT angiography (CTA) and intravascular ultra-sound (IVUS) for coronary calcified lesion .Methods:A total of 50 patients ,who were diagnosed as coronary heart disease (CHD) or suspected CHD in our hospital ,were selected .All patients received coronary CTA and IVUS ex-amination .Characteristics of coronary artery plaques and CT values of different types of plaques were observed , coronary CTA diagnostic effect was evaluated according IVUS as control .Results:There were no significant differ-ence between two methods in plaque area ,plaque burden and lumen area;CT value of calcified plaques was signifi-cantly higher than those of fibrous plaques and fatty plaques [ (725.68 ± 68.42) Hu vs .(58.12 ± 7.05) Hu ,(60.21 ± 6.78) Hu ,P<0.01 both];Sensitivity ,specificity ,accuracy ,positive predictive value and negative predictive val-ue of coronary CTA for diagnosing calcified plaques were 92. 86% ,92. 86% ,92. 86% ,81. 25% and 97. 50% respec-tively .Conclusion:Coronary CT angiography possesses higher diagnostic effect for qualitative and quantitative de-tection of coronary calcified lesions ,which can be regarded as a preferred screening method .
