目的评价９９ｍＴｃＭＩＢＩ（甲氧基异丁基异腈）门控心肌断层显像的临床应用价值。方法以冠状动脉造影为标准，对２７例冠心病患者及１１例对照进行９９ｍＴｃＭＩＢＩ门控心肌断层显像及门控心血池显像。结果门控心肌断层显像较非门控心肌断层显像诊断冠心病有较高的敏感性，门控心肌断层显像与门控心血池显像所测得的ＬＶＥＦ有高度相关性（ｒ＝０．８２，Ｐ＜０．０１）。结论９９ｍＴｃＭＩＢＩ门控心肌断层显像有较大的临床实用价值。
Objective To evaluate the clinical value of 99mTcMIBI (methoxyisobutylisonitrile) gated myocardial tomography. Methods Coronary angiography as the standard, 27 patients with coronary heart disease and 11 controls 99mTcMII gated gated myocardial imaging and gated cardiac pool imaging. Results Gated myocardial imaging was more sensitive than non-gated myocardial tomography in the diagnosis of coronary heart disease. The correlation between gated myocardial perfusion imaging and LVEF measured by gated cardiac pool imaging was highly correlated (r = 0.82, P <0.01). Conclusion 99mTcMIBI gated myocardial tomography has great clinical value.
