Fifty-one patients (42 men; 60 +/- 12 years of age) who had previous stent implantation underwent multislice computed tomographic coronary angiography. All coronary branches > or = 2.0 mm were independently evaluated by 2 observers and screened for in-stent restenosis (> or = 50%) and occlusion. The consensus reading was compared with the quantitative coronary angiogram. Six of the 74 (8.1%) evaluated stents (3 restenoses and 3 occlusions) were significantly diseased. The sensitivity, specificity, and positive and negative predictive values to identify restenosis were 83.3% (95% confidence interval [CI] 35.9 to 99.6), 98.5% (95% CI 92.1 to 100), 83.3% (95% CI 35.9 to 99.6), and 97.3% (95% CI 92.1 to 100), respectively. One in-stent restenosis remained undetected.
51例曾接受支架植入术的患者（42例男性；年龄60±12岁）接受了多层螺旋CT冠状动脉造影。所有直径≥2.0mm的冠状动脉分支由2名观察者独立评估，并筛查支架内再狭窄（≥50%）和闭塞情况。将一致性读片结果与定量冠状动脉造影结果进行比较。74个评估支架中有6个（8.1%）存在明显病变（3例再狭窄和3例闭塞）。识别再狭窄的敏感性、特异性、阳性预测值和阴性预测值分别为83.3%（95%置信区间[CI]35.9至99.6）、98.5%（95%CI 92.1至100）、83.3%（95%CI 35.9至99.6）和97.3%（95%CI 92.1至100）。有1例支架内再狭窄未被检测到。
