【摘要】 目的:比较宝石能谱CT冠脉成像(GCTA)和冠状动脉造影(CAG)诊断冠心病(CHD)的一致性。方法:收集本院拟诊的60例CHD患者,均进行GCTA和冠状动脉造影(CAG)检查,比较两种方法对冠状动脉狭窄诊断的差异性。结果:60例患者中GCTA与CAG均发现狭窄冠脉分支共179支,一致性极高,差异无统计学意义(P>0.05);两种方法对冠脉狭窄各级敏感性和特异度较高。结论:GCTA与CAG诊断冠心病效果一致,且创伤小,有益于诊断冠脉狭窄的定位和冠脉粥样硬化斑块定性诊断,可作为临床筛检无症状冠心病的首选。更多还原

【Abstract】 Objective:To analyze the diagnostic value of gemstone computed tomography angioraphy(GCTA) and coronary arteriography(CAG) for patients with coronary heart disease(CHD).Method:Sixty patients with CHD in our hospital were selected for GCTA and CAG examination,and two methods were compared for the diagnostic consistency of coronary artery stenosis.Result:A total of 179 vascular stenosis were found in 60 CHD patients.GCTA in diagnosis of CHD had a consistency with CAG(P>0.05).And two methods had a perfect sensitivity and specificity in coronary artery stenosis at all levels.Conclusion:GCTA has a consistency with CAG in diagnosis for CHD.Otherwise,GCTA can be used as preferred method for diagnosing CHD for its advantage of little trauma,localization diagnosis for coronary artery stenosis and qualitative diagnosis for coronary atherosclerotic plaques.更多还原
