64层螺旋CT在冠心病诊断中的价值

目的评价64层螺旋CT增强扫描对冠状动脉狭窄的诊断意义。方法156冽患者分别行64层螺旋CT增强扫描和经皮冠状动脉血管造影术（CAG），由两位不知造影结果的医师进行阅片，并以CAG结果作为标准进行对比分析。结果64层螺旋CT判断近段血管狭窄（管腔狭窄≥50％）的灵敏度是：左主干（LM）99％，右冠状动脉（RCA）93％，左前降支（LAD）89％，左回旋支（LCX）82％，判断远段血管狭窄的灵敏度为：RCA56％，LAD45％，LCX43％（P〈0．05）。结论64层螺旋CT增强扫描及其三维重建与冠状动脉血管造影结果具有高度的相关性，通过经静脉增强造影，64层螺旋CT可以清楚显示冠状动脉并判断管腔的狭窄，尤其是近段的重度狭窄。

Diagnostic significance of contrast-enhanced electron 64 bed spiral computed tomograph and coronary angiography in the diagnosis of coronary artery stenosis

Objective To evaluate the application the diagnostic significance of 64 bed spiral computed tomograph for coronary artery stenosis.Methods Coronary angiography and intravenous contrast material enhanced electrocardiographically triggered 64 bed spiral computed tomograph were performed for 156 patieents.The coronary arteries were assessed by two doctors who did not know the result of angiography.Results The sensitivitiees of 64 bed spiral computed tomograph identify proximal stenosed arteries (luminal stenos...
