摘要
目的 :评价多层螺旋CT(MSCT)对冠状动脉的显示能力及对冠状动脉狭窄的诊断价值。 方法 :对 5 2例可疑冠心病患者行MSCT冠状动脉成像 ,其中 2 8例 1周内行选择性冠状动脉造影检查 ,并对检查结果进行分析和评价。 结果 :5 2例患者共显示 5 11个血管节段 ,其中 82 %的血管节段具有影像诊断价值。MSCT诊断≥ 5 0 %冠脉狭窄程度的敏感性为 70 .97% ,特异度为 98.75 % ,阴性预测值为 96 .34%。 结论 :MSCT冠状动脉成像是一项有潜力的、无创性的检查方法 ,适用于心率较慢患者冠心病的筛查。
Objective: To evaluate the ability of Multi-slice spiral CT (MSCT) on display of coronary artery and the feasibility of MSCT in diagnosis of coronary stenosis. Methods: 52 patients with suspected coronary heart disease and 3 patients underwent MSCT coronary angiography. 28 of them were also investigated with selective coronary angiography (SCA). Results: With MSCT angiography, 82% coronary segments were assessable. The sensitivity for diagnosing significant coronary stenosis (≥50% lumen reduction) was 70.97%, the specificity was 98.75%. The negative predictive value was 96.34%. Conclusion: MSCT coronary angiography, non-invasive、 convenient and reliable, is a potential method for screening coronary artery disease and following-up post-operative PTCA, especially in patients with low heart rates.
