64层螺旋CT冠状动脉成像对冠心病的诊断价值

The Diagnostic Value of 64-slice Spiral Computed Tomography to Coronary Heart Disease

目的:评价64层螺旋CT对冠心病的诊断价值。方法:对25例典型病例的CT图片进行分析、总结,观察64层螺旋CT对冠状动脉的管腔狭窄程度及冠脉内斑块性质的显示能力,并对桥血管和支架通畅性进行观察。结果:近端冠脉中度以上狭窄的敏感度、准确度、阳性预测值分别为93.5%,90.3%,88.5%,对左主干及前降支病变诊断价值较高;对冠状动脉内软斑块显示较佳;对桥血管及支架通畅和有无再狭窄显示良好。结论:MSCT冠状动脉成像在冠心病筛查及冠状动脉支架术后和搭桥术后的随访发挥重要作用。

Objective：To study the diagnose value of 64-slice spiral CT for coronary heart disease.Methods：The CT pictures of 25 typical cases of coronary heart disease were analyzed so as to survey the displaying ability coronal arterial stenosis,its degree and the character plaques,the patency of bypass graft and stents by 64-slice spiral CT.Results： The sensitivity,accuracy,positive predictive value for RCA1 narrow above moderate was 93.5%,90.3%.88. 5%respectively.For LM and LAD,its diagnose value was high.The coronary soft or fibrous plaque,stent and bypass graft were displayed well.Conclusion：MSCT plays an important role in filtering coronary heart disease and reexamination after stents and bypass.
