~(201)Tl 心肌显像能判断“冬眠”心肌,但价格昂贵,尚不能在国内推广应用。~(99m)Tc-甲氧基异丁基异腈(MIBI)在动物实验中能灵敏地检测存活心肌。笔者对~(201)Tl 静息及再分布显像与~(99m)Tc-MIBI 静息心肌显像进行了定量比较,以观察3种显像间定量分析结果及其在心肌梗塞区存活心肌判断中的差异。资料与方法1.临床资料:1994年4月～1995年2月在我室进行心肌显像的18例心肌梗塞患者,均为男性,平均年龄59(38～69)岁,临
~ (201) Tl myocardial imaging can determine “hibernation ” myocardium, but expensive, yet can not be applied in the country. ~ (99m) Tc-methoxyisobutylisonitrile (MIBI) can detect viable myocardium sensitively in animal experiments. We quantitatively compared the resting and redistributed imaging of ~ (201) Tl with ~ (99m) Tc-MIBI resting myocardial imaging in order to observe the quantitative results of the three images and their survival in myocardial infarction Differences in judgment. Materials and Methods 1. Clinical data: 18 patients with myocardial infarction who underwent myocardial imaging in our hospital from April 1994 to February 1995 were male, with an average age of 59 (38-69) years
