摘　　要：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。Myocardia] perfusion imaging of single photon emission computed tomography (SPECT) with thallium-201 was carried out in two groups of patients,subsequently submitted to diagnostic coronary angiography. SPECT was performed in group A (41 patients) after iv infusion of dipyridamole and in group B(162 patients) after tracer injection at maximal ergometric exercise. The sensitivity for the left anterior descending artery was 77% in group A and 79% in group B; specificity was 80% and 96% .respectively. Sensitivity for the right coronary artery was 91% in group A and 85% in group B; specificity was 81% and 73%,respectively. For the left circumflex artery sensitivity was 65% for group A and 67% for group B,while specificity was 89% and 88% , respectively. Myocardial SPECT results after ergometric exercise and dipyridamole infusion turned out to be almost superimposable. Dipyridamole stress might be considered appropriate as a provocative test when physical exercise cannot be carried out.
