本文报道了１００例９９ｍＴｃ—ＭＩＢＩ次极量运动心肌断层显像与冠状动脉造影的对比研究，结果表明，９９ｍＴｃ一ＭＩＢＩ次极量运动心肌断层显像对陈旧性心肌梗塞病变的检出率和对病变范围的估价优于心电图。本组心绞痛患者９９ｍＴｃ—ＭＩＢＩ心肌断层显像诊断敏感性为９３％，特异性７９％，运动心电图对心绞痛诊断的敏感性为５９％，特异性７９％。９９ｍＴｃ—ＭＩＢＩ次极量运动心肌断层显像是判断心肌缺血敏感可靠的方法。
This paper reports 100 cases of 99mTc-MIBI submaxillary myocardial imaging and coronary angiography contrast study showed that 99mTc a MIBI subacute myocardial perfusion imaging on the detection of old myocardial infarction lesions and The evaluation of the extent of the lesion is superior to the electrocardiogram. The diagnostic sensitivity of 99m Tc-MIBI myocardial imaging in patients with angina in this group was 93% and specificity was 79%. The sensitivity of exercise ECG in diagnosing angina was 59% and the specificity was 79%. 99mTc-MIBI submaximal myocardial perfusion imaging is a sensitive and reliable method to determine myocardial ischemia.
