本文比较了潘生丁-~(201)铊单光子发射型计算机心肌断层显象(A组,41例)与运动心肌断层显象(B组,162例)对冠心病的诊断价值。结果表明:以冠脉造影结果为标准A组中前降支检出的敏感性、特异性分别为77％和80％;B组分别为79％和96％;右冠脉病变检出的敏感性和特异性,A组为91％和81％,B组为85％和73％;左旋支病变检出的敏感性和特异性,A组为65％和89％,B组为67％和88％,均无显著性差异(P均>0.05)。提示潘生丁-~(201)铊心肌断层显象可与运动心肌断层显象相媲美,对一些不适于运动试验而疑似冠心病患者的诊断有重要意义。
This study compared the diagnostic value of dipyridamole ~ 201 thallium single photon emission computed tomography (group A, n = 41) and motor myocardium (group B, n = 162) for coronary heart disease. The results showed that the sensitivity and specificity of detection of anterior descending coronary artery in group A were 77% and 80%, respectively. The sensitivity of right coronary artery was 79% and 96% respectively in group B 91% and 81% in group A, 85% and 73% in group B, respectively. The sensitivity and specificity of detecting left-sided lesions were 65% and 89% in group A and 67% in group B 88%, no significant difference (P> 0.05). Tip dipyridamole ~ 201 thallium myocardial imaging can be compared with the performance of myocardial imaging, is not suitable for exercise testing and suspected coronary heart disease diagnosis is of great significance.
