摘　　要：目的探讨16排螺旋CT冠脉成像对冠心病支架植入术后再狭窄的诊断价值。方法对2009-2010年我院65例临床冠心病支架植入术后再狭窄的患者进行常规冠脉造影,全部患者在两周后行16排CT冠脉成像对比。结果以常规冠状动脉造影为标准,16排螺旋CT冠脉造影诊断冠心病支架植入术后再狭窄敏感率,为中度狭窄的敏感性和特异性分别为92.9%和84.7%,阳性预测值为69.6%,阴性预测值为96.9%;重度狭窄的敏感性和特异性为88.2%和98.9%。结论 16排螺旋CT冠脉成像对冠心病支架植入术后支架内、外管腔狭窄显影均有较高的准确率,可作为冠心病患者支架植入术后再狭窄无创检查和冠脉支架术后随访手段。Objective To investigate the 16-slice CT imaging of coronary artery disease coroary artery restenosis after stent implantation diagnosis.Methods：65 patients in our hospital in 2009-2010 Clinical restenosis after coronary stent implantation in patients with normal coronary angiography,all patients underwent 16-slice CT in the two weeks of coronary artery imaging contrast.Results：Conventional coronary angiography as the standard,16-slice spiral CT coronary angiography in the diagnosis of restenosis after cor3nary stent implantation was sensitive to moderate stenosis of the sensitivitv and specificity were 92.9%and 84.7%,positive predictive value 69.6%,negative predictive value 96.9%;severe stenosis of the sensitivity and specificity of 88.2%and 98.9%.Conclusion：16一slice spiral CT imaging of coronary stent coronary stent implantation,the outer luminal stenosis has a higher accuracy rate imaging can be used as coronary stent restenosis in patients with non—invasive examination and coronary stent postoperative follow—up means.
