摘要
目的:探讨128层螺旋CT冠状动脉成像(128-SCTCA)对2型糖尿病的冠状动脉病变的诊断价值。方法:收集41例2型糖尿病合并冠心病患者的影像资料,评估128-SCT冠状动脉成像在2型糖尿病合并冠心病患者的冠状动脉病变的准确性。结果:128-SCTCA诊断冠状动脉≥70%、≥50%、<50%狭窄性病变敏感性依次为90.4%、94.2%、83.1%,特异性依次为95.1%、94.8%、92.6%;阳性预测值依次为87.4%、93.0%、75.0%。阴性预测值依次为96.3%、95.7%、95.3%。结论:128-SCTCA是诊断2型糖尿病合并冠心病冠状动脉狭窄性病变可靠的、无创的检查方法。
Objective： It is to discussion on 128- slice spiral CT coronary artery Ima- ging（ 128 - SCTCA ） in diagnosis of coronary artery disease in type 2 diabetes. Methods： Collection of 41 patients with type 2 diabe- tes mellitus complicated with coronary heart disease image data, assessment 128 -SCT angiography of coronary artery in coronary artery disease in type 2 diabetes mellitus complicated with coronary heart disease pa- tients for accuracy. Results： 128 - SCTCA diagnosis of coronary artery ≥ 70%, ≥ 50%, 〈 50% stenosis sensitivity followed by 90.4%,94.2% , 83. 1%, specific fol- lowed by 95. 1% 、94.8% 、92.6% ; Positive predictive percentiles followed by the 87.4% , 93.0% , 75.0% , negative predic- tive percentiles of 96.3% ,95.7% ,in turn. Conclusion： 128 -SCTCA is the reliable, non - invasive method for diagnosing type 2 diabetic patients with coronary heart disease with coronary stenosis.
