摘　　要：目的分析多层螺旋CT(MSCT)冠状动脉造影在评价冠状动脉狭窄中的准确性。方法选取本院2017年4月至2018年10月收治的94例患者作为研究对象,以SAC结果为“金标准”,分析MSCTA诊断冠状动脉不同狭窄程度的准确性及各支狭窄的准确性。结果MSCTA诊断冠状动脉无狭窄的准确率为90.91%,诊断冠状动脉轻度、中度、重度狭窄的准确率分别为87.50%、91.67%、91.30%;MSCTA诊断左主干(LMA)、左前降支(LAD)、左回旋支(LCX)、右冠状动脉(RCA)狭窄的准确率分别为100.00%、82.75%、83.78%、87.10%。结论MSCTA在诊断冠状动脉狭窄方面具有较高的准确性,且安全可靠、无创伤、经济实惠,临床应用价值较高,值得推广。Objective To analyze the accuracy of coronary angiography of multi-slice spiral CT(MSCT)in evaluating coronary stenosis.Methods 94 patients admitted to our hospital from April 2017 to October 2018 were selected as the research subjects.The SAC results were used as the gold standard to analyze the accuracy of MSCTA in the diagnosis of varying degrees of stenosis and in the diagnosis of stenosis of each branch.Results The accuracy of MSCTA in the diagnosis of non-coronary stenosis was 90.91%,and the accuracy of MSCTA in the diagnosis of mild,moderate,and severe coronary stenosis was 87.50%,91.67%,and 91.30%,respectively.The accuracy of MSCTA in the diagnosis of the left main artery(LMA),left anterior descending branch(LAD),left circumflex branch(LCX),and right coronary artery(RCA)stenosis was 100.00%,82.75%,83.78%,and 87.10%,respectively.Conclusion MSCTA has high accuracy in the diagnosis of coronary artery stenosis,is safe,reliable,non-invasive,and economical,and it has high clinical application value.It is worthy of widespread promotion.
