摘　　要：目的 :对照分析99m锝—MIBI心肌显像与冠状动脉造影检查结果 ,评价99m锝—MIBI心肌显像对冠心病的诊断价值。材料与方法 :12 7例患者 ,4周内行冠状动脉造影及99m锝—MIBI心肌显像检查 ,对比二种结果并分析冠脉病变支数及性别 ,易患因素等与核素检查结果的关系。结果 :核素心肌显像检查的敏感性为 82 2 8% ,特异性为 6 0 42 % ,核素结果与冠脉造影结果一致率在单支病变最高 ,为 89 6 6 %。在双支病变次之 ,为 83 33%。在三支病变最低 ,为 6 8 97% ,P <0 0 5。性别、吸烟、高脂血症、糖尿病不影响二种检查结果的一致率。结论 :99m锝—MIBI心肌显像具有较理想的敏感性和可接受的特异性 ,并安全可行 ,是诊断冠心病的重要手段。Purpose:To evaluate the diagnostic value of 99m Tc-MIBI myocardial tomography(MT) in coronay heart disease(CAD) comparing with coronary angiography (CAG).Materials and Methods:Both 99m Tc-MIBI myocardial tomography and coronary angiography were performed in 127 casea with in 4 weeks.The results are compared,Their relations with sex etc.factors of CAD are analysed.Results:The sensitivity and specificty of MT are 82 28% and 60 42%,The accordance rate of the two exams is the highest in single-vessel disease(89.66%),higher in double-vessel disease(83.33%),and as high as 68.97% in triple-vessel disease(P<0 05).Sex smoking,hypertension,hyperlipidemia,disbetes mellitus are not related to the accordance rate.Conclusion: 99m Tc—MIBI myocardisl tomography shows a comparably ideal sensitivty and an acceptable specificity,and can be used as an important diagnostic method for CAD.
