摘　　要：目的:探讨64排螺旋CT冠脉成像(CTA)在诊断冠心病中的临床应用价值。方法:选取行CTA检查后2周内行冠状动脉造影(CAG)患者112例作为研究对象,以CAG结果为金标准,对CTA显示冠状动脉不同分支血管进行分级评估。结果:所评估目标血管共1290支,CTA显示病变血管354支,CAG显示病变血管348支。CTA对于不同狭窄程度血管显示的敏感性、特异性、准确性、阳性预测值、阴性预测值分别为:轻度77.78%、98.43%、96.51%、65.89%、98.67%,中度85.51%、97.40%、96.12%、79.73%、98.25%,重度68.84%、97.74%、94.65%、78.51%、96.32%,且两种检查方法在判定冠状动脉不同狭窄程度上的差异均无统计学意义(P>0.05)。结论:64排CTA对冠状动脉血管评估具有较高的准确性,可以作为临床冠心病筛查及血运重建后复查的首选检查方式。Objective： To analyze the accuracy of multi slice spiral CT coronary artery in diagnosis of coronary heart disease and in judgment of artery stenosis degree.Method：112 patients with the inspection of coronary angiography（CAG） after 2 weeks in our hospital were collected,they accepted the inspection of coronary artery CTA,CAG was used as the gold standard to evaluate the grading of different branches of coronary artery by CTA.Result： A total of 1290 vessels were assessed, CTA showed vascular lesions of the 354 branches,CAG showed vascular lesions of the 348 branches.Referring to the result of CAG inspection, the sensitivity,specificity,accuracy,positive predictive,and negative predictive value of CTA inspection were respectively： mild stenosis 77.78%,98.43%,96.51%,65.89%,98.67%;moderate stenosis 85.51%,97.40%,96.12%,79.73%,98.25%;severe stenosis 68.84%,97.74%,94.65%,78.51%,96.32%,two methods had no statistical discrepancies in diagnosis of coronary heart disease and in judgment of artery stenosis degree（P〉0.05）.Conclusion：The diagnostic accuracy of spiral CT coronary angiography is similar to that of percutaneous selective coronary angiography,and it is a noninvasive and reliable method for the screening of coronary heart disease.
