对７０例９９ｍＴｃ－ＭＩＢＩ心肌灌注断层显像潘生丁试验（ＣＴＤ）及ＥＣＧ结果与冠状动脉造影（ＣＡ）进行对照分析，结果表明：ＣＴＤ检测冠状动脉管腔狭窄≥５０％病变的灵敏度和特异性分别是８８％和９３％，明显高于ＥＣＧ（５２％和７７％），检出左前降支（ＬＡＤ）、左回旋支（ＬＣＸ）及右冠状动脉（ＲＣＡ）病变的灵敏度分别为８２％、８４％及８３％；检测冠状动脉单支病变的灵敏度为８２％，检出轻、中、重度狭窄的灵敏度分别是４４％、８１％、１００％．对１７例经皮腔内冠状动脉成形术（ＰＴＣＡ）患者的术前术后ＣＴＤ结果进行了分析．结果表明ＣＴＤ对于诊断冠心病的灵敏度和特异性都很高，对筛选ＰＴＣＡ术前病人以及手术疗效评价和追踪观察有很重要的临床价值．
70 cases of 99mTc-MIBI myocardial perfusion tomography dipyridamole test (CTD) and ECG results and coronary angiography (CA) were analyzed, the results showed that: CTD detection of coronary stenosis ≥50% sensitivity and specificity of the disease were Were 88% and 93%, respectively, which were significantly higher than those of ECG (52% and 77%). The sensitivity of detection of left anterior descending coronary artery, left circumflex artery and right coronary artery were 82% and 84%, respectively % And 83%, respectively. The sensitivity of detecting coronary artery single vessel disease was 82%, and the sensitivity of detecting light, medium and severe stenosis was 44%, 81% and 100% respectively. Preoperative and postoperative CTD results were analyzed in 17 patients undergoing percutaneous transluminal coronary angioplasty (PTCA). The results showed that the sensitivity and specificity of CTD for the diagnosis of coronary heart disease are very high. It has important clinical value in screening preoperative PTCA patients and the evaluation of surgical efficacy and follow-up.
