摘　　要：目的:探讨在不典型性胸痛的冠心病病人诊断鉴别中使用64排螺旋CT冠脉成像的价值。材料与方法:随机选取我院近年来收治的80例不典型性胸痛病人,采用64排螺旋的CT冠状动脉成像,之后使用选择性的冠状动脉造影,即SCA,在选择性冠状动脉造影的基础上评价64排螺旋CT成像的准确性。结果:64排螺旋的CT冠状动脉成像分别具有91%的准确度,80%的特异度和97%的敏感度;64排螺旋的CT冠状动脉成像分别具有59%的轻度狭窄确诊率和90%的中度及以上狭窄确诊率,具有显著性差异(P<0.01);而对于右冠状动脉和左回旋支,64排螺旋的CT冠状动脉成像判断病变的能力较弱。结论:64排螺旋的CT冠状动脉成像基本上可以作为不典型性胸痛的冠心病病人筛查手段。Purpose： To assess the value of differential diagnosis of 64-slice spiral computed tomography （CT） coronary angiography in patients with atypical chest pain. Materials and Methods： Eighty patients underwent selective coronary angiography（SCA） after 64-slice spiral CT coronary angiography. The accuracy of 64-sllice spiral CT was assessed by SCA. Results： The accuracy, specificity and sensitivity of 64-slice spiral CT were 91%, 80% and 97% respectively. The correct ratio in no significant stenoses （under 50% luminal narrowing）and significant stenoses （over 50% luminal narrowing） of 64-slice spiral CT were 59% and 90% respectively（ P 〈 0. 01 ）. The detection ability of 64-slice spiral CT was relatively weak in fight coronary artery and left circumflex artery. Conclusion： The 64-slice spiral CT can be an useful method for the detection of the coronary heart disease patients with atypical chest pain.
