摘　　要：目的分析Stellar光子探测器双源CT冠状动脉成像(DSCT)对冠心病患者的临床诊断价值。方法回顾性分析200例疑似或确诊的冠心病患者临床资料,所有患者分别行冠状动脉造影(CAG)和DSCT,并以CAG检查结果为金标准对DSCT诊断冠状动脉狭窄情况进行评价。结果DSCT检出659个狭窄段,灵敏度为84.94%(581/684),特异度为95.66%(1721/1799),阳性预测值为88.16%(581/659),阴性预测值为94.35%(1721/1824)。诊断符合率为92.71%(2302/2483)。DSCT检测每支冠状动脉灵敏度为86.98%(274/315),特异度为93.33%(266/285),阳性预测值为93.52%(274/293),阴性预测值为86.64%(266/307)。诊断符合率为90.00%(540/600)。通过对比DSCT对不同部位冠状动脉诊断效能发现,DSCT诊断左主干、前降支及回旋支的诊断符合率较高;诊断前降支、回旋支和右冠状动脉的灵敏度较高,诊断左主干的灵敏度较低;诊断左主干、前降支、回旋支和右冠状动脉的特异度均较高。结论DSCT诊断冠心病效果良好,安全性更高,值得推广。Objective To analyze the value of Stellar photon detector with dual-source CT(DSCT)coronary imaging in clinical diagnosis of patients with coronary heart disease.Methods The clinical data of200 patients with suspected or confirmed coronary heart disease were retrospectively analyzed.All patients received coronary angiography(CAG)and DSCT coronary imaging.The results of CAG examination were used as the"gold standard"to evaluate the diagnosis of coronary stenosis by DSCT.Results DSCT detected659 stenosis segments,the sensitivity was 84.94%(581/684),the specificity was 95.66%(1721/1799),the positive predictive value was 88.16%(581/659),and the negative predictive value was 94.35%(1721/1824).The diagnosis coincidence rate was 92.71%(2302/2483).The sensitivity of DSCT to detect each coronary artery was 86.98%(274/315),the specificity was 93.33%(266/285),the positive predictive value was 93.52%(274/293),and the negative predictive value was 86.64%(266/307).The diagnostic coincidence rate was 90.00%(540/600).By comparing the diagnostic efficiency of DSCT in different parts of coronary artery,it was found that the diagnostic coincidence rate of DSCT in the diagnosis of left main artery,anterior descending artery and circumflex branch was higher;the sensitivity of diagnosing anterior descending artery,circumflex branch and right coronary artery was higher,while the sensitivity of diagnosing left main artery was lower;the specificity of diagnosing left main artery,anterior descending artery,circumflex branch and right coronary artery was high.Conclusion DSCT has a good effect in diagnosing coronary heart disease with higher safety and is worthy of promotion.
