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)

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

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％。

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.
