摘　　要：目的探讨16层螺旋CT评价冠状动脉支架内再狭窄的应用价值。方法对24例冠状动脉支架术后患者行心电门控16层螺旋CT冠状动脉成像,以选择性冠状动脉造影结果为对照,分析16层螺旋CT冠状动脉成像对诊断冠状动脉支架内再狭窄的应用价值。结果16层螺旋CT冠状动脉成像诊断冠状动脉支架内再狭窄≥50%的敏感度、特异度、阳性预测值和阴性预测值分别为100%、81%、58%、100%。结论16层螺旋CT冠状动脉成像对冠状动脉支架术后患者的随访有重要价值。Objective To investigate the clinical application of 16 - slice spiral CT coronary angiography for coronary stent restenosis. Methods 16 - slice spiral CT coronary angiography was performed with ECG - gated in 24 cases undergone post - operation of coronary stent, so that to analyse the applied value of 16 -slice spiral CT coronary angiography in evaluating coronary stent restenosis in comparison with the findings of selective coronary angiography（SCA）. Results The sensitivity , specificity , positive predictive value and negative predictive value for the detection of≥50% restenosis with 16 - slice spiral CT coronary angiography were 100% , 81% , 58% and 100% , respectively. Conclusion 16 - slice spiral CT coronary angiography with ECG - gated retrospectively may be useful in following up in patients with suspected coronary restenosis .
