摘要

探讨99mTc-甲氧基异丁基异腈（MIBI）门控心肌灌注显像所获得的室壁增厚信息在判断冠心病心肌梗死患者中存活心肌的价值。26例确诊的冠心病心肌梗死的男性患者

均在2周内完成12导联心电图（EKG）、99mTc-MIBI静息门控心肌灌注显像、18F-脱氧葡萄糖（FDG）心肌代谢显像

所有病人均接受冠状动脉造影（CAG）。在双核素心肌显像结果提示为缺血存活心肌的心肌节段中

MIBI分布缺损但室壁增厚（WT）正常的心肌节段占双核素显像结果提示为缺血存活心肌节段的68.2%;在双核素心肌显像结果提示为梗死心肌的心肌节段中

MIBl分布缺损且WT异常的心肌节段占双核素显像结果提示为梗死心肌节段的96.8％。静息门控心肌灌注显像所获得的血流灌注和室壁增厚信息与99Tc-MIBI/18F-FDG双核素心肌显像结果具有较高的符合率

故在单纯的心肌血流灌注图像的基础上

结合室壁增厚信息与传统的心肌灌注显像相比有助于检出更多的存活心肌。

Abstract

To investigate the value of assessing viable myocardium by wall thickening(WT)coming from 99mTC-MIBI ECG-gated myocardial perfusion imaging(G-MPI)in myocardial infarction

twenty-six patients with myocardial infarction underwent rest 99mTc-MIBI G-MPI

EKG

18F-FDG myocardial metabolic imaging and CAG within two weeks.For determining viable myocardium

the segments of myocardium with abnormal MIBI uptake and normal wall thickening(WT)were 68.2% of ischemic viable myocardium demonstrated by 99mTc-MIBI/18F-FDG dual isotope tomography.The segments of myocardium with abnormal MIBI uptake and abnormal WT were 96.8% of infarct myocardium demonstrated by dual isotope tomography．Use of wall thickening coming from 99mTc-MIBI G-MPI may help to select more viable myocardium as compared with conventional myocardial perfusion imaging.
