潘生丁ECT显像诊断冠心病临床可行性研究：附110例冠脉造影对照报告

110例疑冠心病病人以冠状动脉造影为对照，研究潘生丁核素心肌断层显像在诊断冠心病中的临床可行性。73例冠脉造影阳性（50％以上狭窄）及37例造影阴性病例中，潘生丁心肌显像检出的敏感性为95．3％，特异性为89．2％。单支、双支及三支病变检出的敏感性分别为92．7％、100％、100％。受累血管检出的敏感性分别为左前降支84．2％，回旋支82．1％，右冠状动脉90．6％。

Clinical Feasibility of Dipyridamole SPECT Myocardial Imaging in Detecting Coronary Artery Disease (CAD)-Comparision With Coronary Angiography in 110 Patients

To compare with the results of coronary angiongraphy, We evaluated the value ofdipyridamole SPECT myocardial imaging in detecting coronary artery disease (CAD) in 110 pa-tients. In detection of CAD, coronary angiongram and myocardial perfusion imaging were analy-sised. The sensitivity and specificity of dipyridamole SPECT mycardial imaging was 95. 3% and89. 2%, respectively. In diagnosing whether diseased or not, single, double, triple vessel dis-eases, the sensitivity was 92. 7%, 100% and 100%, respectively. In identifying left anterior de-scending, left circumflex and right coronary artery, the sensitivity was found to be 84. 2%,82. 1 % and 90. 6%respectively. The test itself was safe. We concluded that dipyridamole SPECTmycardial perfusion imaging was a quite valuable, noninvasive method in detecting coronaryartery disease.
