目的为TOSHIBAGCA -90 1A/SA型SPECT建立99mTc-MIBI心肌灌注显像诊断标准。方法收集 1 996～ 1 997年间本院住院病人中做99mTc-MIBI心肌血流灌注显像的病例并按自定“标准”作出诊断和分析的共 1 3 3例 ;同时做过SPECT和CAG (或PTCA)的共 61例 (4 5 86% ) ;所有病例的SPECT检查均符合质控条件。结果该标准诊断CAD符合率 93 1 8%、心肌梗死符合率 1 0 0 % ;灵敏度 96 67%、特异性 91 0 0 %、假阳性率 0 %、假阴性率 3 2 8% ;在高血压病、其它心脏病中可出现阳性 ,在非心脏病性疾病中没有出现阳性病例。结论从 61例有CAG对照的病例和非心脏病性疾病来看 ,该标准具有一定的参考价值。
Objective To establish diagnostic criteria of 99m Tc-MIBI myocardial perfusion imaging for TOSHIBAGCA-90 1A / SA SPECT. Methods A total of 133 cases of 99mTc-MIBI myocardial perfusion imaging in inpatients from 1996 to 1997 in our hospital were collected and diagnosed and analyzed according to self-defined criteria. SPECT and CAG Or PTCA) in 61 cases (456%). SPECT examination in all cases were in line with the quality control conditions. Results The diagnostic accuracy of CAD in this standard was 93.1%, the coincidence rate of myocardial infarction was 100%, the sensitivity was 96.67%, the specificity was 91.0%, the false positive rate was 0% and the false negative rate was 38.2% Disease, positive in other heart disease, no positive cases in non-heart disease. Conclusions From 61 cases with CAG control and non-heart disease, the standard has some reference value.
