摘　　要：目的探讨99mTc-MIBI(甲氧基异睛)心肌灌注断层显像与冠状动脉造影不一致的临床意义。方法136例临床诊断为冠心病患者,于冠状动脉造影术(CAG)前2周内行99mTc-MIBI心肌灌注断层显像(运动或药物负荷及静息显像)。以CAG为金标准,分析99mTc-MIBI心肌灌注断层显像假阳性与假阴性的临床意义。结果两者不相符合13例,99mTc-MIBI心肌灌注断层显像阳性而冠状动脉正常者10例,99mTc-MIBI心肌灌注断层显像阴性而冠状动脉造影阳性者3例。结论99mTc-MIBI心肌灌注断层显像阴性而冠状动脉造影阳性提示冠脉临界病变,99mTc-MIBI心肌灌注断层显像阳性而冠状动脉造影阴性提示冠脉微循环灌注不足。Objective To evulate the clinical significance of the inconsistent between ^99mTc-MIBI myocardial perfusion imaging and coronary angiography. Methods 136 patients with clinical diagnosis of coronary heart disease, coronary angiography （CAG）were performed before exercise ^99mTc-MIBI myocardial perfusion imaging （treadmill or drug stress and resting imaging）within two weeks. As CAG for the gold standard, to analyse the clinical significance of ^99mTc-MIBI myocardial perfusion imaging false positive and false negative results. Results The two incompatible with 13 cases, ^99mTc-MIBI myocardial perfusion imaging and coronary artery was normal in 10 cases,^99mTc-MIBI myocardial perfusion imaging negative and positive coronary angiography in three cases, Conclusion ^99mTc-MIBI myocardial perfusion imaging negative and positive coronary angiography prompted critical coronary lesions, ^99mTc-MIBI myocardial perfusion imaging positive and negative coronary angiography prompted coronary microcirculation hypoperfusion.
