摘　　要：目的评价心电门控的多层螺旋CT冠状动脉造影在诊断冠状动脉狭窄程度中的临床应用价值及其局限性。方法对101例患者（临床诊断或疑似冠心病）均行多层螺旋CT冠状动脉造影和导管法冠状动脉造影（CAG），前后时间不超过2周，将冠状动脉的狭窄程度分为轻度（〈50％）、中度（50％～75％）及高度（≥75％），以CAG结果为“金标准”，将二者结果对照，进行诊断实验评价。结果在101例患者的373支可评估冠状动脉血管中，多层螺旋CT判断冠状动脉轻度狭窄的灵敏度、特异度、阳性预测值、阴性预测值分别为67．3％、81．4％、52．1％、89．2％；中度狭窄为84．6％、90、3％，65、7％、96．4％；重度狭窄为90．4％、94、5％、82．4％、97．2％。结论与导管法冠状动脉造影相比，多层螺旋CT冠状动脉造影是一门可较好显示冠状动脉管腔狭窄的非侵入性技术，对中、重度冠状动脉狭窄的诊断更为可靠。Objective To evaluate the clinical application value of multi-slice spiral CT coronary angiography with retrospectively ECG-gated. Methods One hundrud and one consecutive patients were referred for catheterization coronary angiography（CAG） and 16-slice spiral CT coronary angiography to detect coronaW disease in 2 weeks, and the results of the both methods were compared. According to results of CAG, the stenosis grade of coronary artery is classitied as mild,medium and high-grade. Results 112 373 coronary arteries of 101 parents that can be evaluated, the sensitivity, specificity, positive and negative predictive value to identify mild, medium and high-grade stenosis of coronary artery with multi-slice MSCT were 67.3% ,81.4%, 52.1%, 89.2% ; 84.6%, 90.3%, 65.7%, 96.4% ; 90.4%, 94.5% ,82.4% ,97.2% respectively. Conclusion MSCF with retrospective F, CG gating is a non-invasive method to permit the detection of coronary artery stenoses, It had clinical applicable value to suspect coronary artery disease and for pre-eoronary intervention operative examination.
