64排128层螺旋CT冠脉动脉成像与冠脉造影在冠脉狭窄的诊断价值及意义

Diagnostic value and significance of 64 slice 128 slice spiral CT coronary angiography and coronary angiography in coronary artery stenosis

目的:探讨64排128层螺旋CT冠脉动脉成像与冠脉造影在冠脉狭窄的诊断价值。方法:选取100例于2015年6月—2017年6月在我院诊疗的冠心病患者作为本次研究的对象,结合患者的临床资料,所有患者均行64排128层螺旋CT冠脉动脉成像术进行检查,并于28天后再次行冠脉造影进行检查,对所获得的影像检查资料进行统计分析。结果:冠脉造影进行检查结果显示,采用64排128层螺旋CT冠脉动脉成像诊断冠脉狭窄的Se(灵敏度)为90.48%、Sp(特异度)为92.09%,PV+(阳性预测值)为86.93%、PV-(阴性预测值)为94.33%。结论:使用64排128层螺旋CT冠脉动脉成像术对冠心病患者进行检查,可以准确的做出冠脉狭窄的诊断结论,且检查费用相对低廉,仅为传统冠脉造影的1/4～1/3,容易人们所接受。可以在行冠脉造影检查前使用,进行冠脉狭窄的筛查,在临床工作中值得推广使用。

Objective To evaluate the diagnostic value of 64 slice 128-slice spiral CT angiography and coronary angiography in coronary stenosis.Methods 100 patients with coronary heart disease(CHD) from June 2015 to June 2017 were selected as the subjects of this study.All patients underwent 64-slice 128-slice spiral CT coronary arteriography combined with clinical data.Coronary angiography was performed again 28 days later.Results The results of coronary angiography showed that 64-slice 128-slice spiral CT angiography was used to diagnose coronary artery.The se(sensitivity) of coronary stenosis was 90.48% and the specificity was 92.09% PV+(positive predictive value) was 86.93% PVnegative predictive valuewas 94.33%.Conclusion Using 64-slice 128-slice spiral CT coronary arteriography in coronary artery disease patients can accurately make the diagnosis conclusion of coronary artery stenosis, and the examination cost is relatively low, it is only1/4 ~ 1/3 of traditional coronary angiography,which is easily accepted by people.Can be used before coronary angiography,coronary artery stenosis screening,in clinical work is worth popularizing.
