128排螺旋CT冠状动脉成像技术诊断冠状动脉狭窄的效果分析

目的:探讨128排螺旋CT冠状动脉成像技术诊断冠状动脉狭窄的效果及应用价值。方法:选取2016年3月-2017年5月我院收治的88例疑似冠心病患者,均行128排螺旋CT冠状动脉成像(CTA)与冠状动脉造影(CAG)检查,将两种检查方法的诊断结果进行对比分析。结果:CTA检查对轻度狭窄的检出率为14.77%,与CAG检查结果相比差异显著(P<0.05),在中度狭窄、重度狭窄及闭塞中的检出率与CAG检查相似,差异无统计学意义(P<0.05)。CTA检查灵敏度为96.0%,特异度为78.57%。结论:128排螺旋CT冠状动脉成像技术在冠状动脉狭窄中的检查灵敏度、特异度与准确性较高,具有检查创伤小、操作简单的特点,临床应用价值较高。

Objective:To investigate the effect of 128-slice spiral CT coronary artery imaging in the diagnosis of coronary artery stenosis and its application value.Methods:Eighty-eight suspected coronary heart disease patients admitted to our hospital from March 2016 to May 2017 were selected for 128-slice spiral CT coronary artery imaging(CTA)and coronary angiography(CAG)examinations.Diagnostic results were compared and analyzed.Results:The detection rate of CTA was 14.77%for mild stenosis,which was significantly different from that of CAG(P<0.05).The detection rate in moderate stenosis,severe stenosis,and occlusion was similar to that of CAG.No statistical significance(P<0.05).The sensitivity of CTA examination was 96.0%and the specificity was 78.57%.Conclusion:The 128-slice spiral CT coronary artery imaging technique has higher detection sensitivity,specificity and accuracy in coronary artery stenosis.It has the characteristics of small examination,simple operation and high clinical value.
