^(99m)Tc-MIBI心肌断层显像在冠心病诊断上的应用

Application of ~99MTc - MIBI myocardial tomography imaging for the diagnosis of coronary heart disease

报道了冠心病、冠心病合并高血压和心肌梗塞(共119例),通过^(99m)Tc-MIBI心肌断层显像,得到静息心肌断层对冠心病的检出率为70.21％;运动负荷心肌断层能进一步提高它的检出率,而心电图亚极量负荷试验对它的检出率仅为63.8％。说明核素心肌断层显像是一项灵敏度高、特异性强的诊断冠心病的无创伤性检查方法。

99mTc - MIBI myocardial tomography imaging was obtained from 119 cases with Sopha Medical SPECT system. 38 cases of coronary heart diseases, 33 cases of coronary heart diseases combined with hypertension and 48 cases of myocardial infarction were diagnosed according to clinical symptoms and signs, ECG,exercise ECG(treadmill test)and other laboratory studies. The results showed that positive rate of myocardial tomogarphy imaging for detecting coronary heart disease was 70. 21% at rest, and the positivity can be further increased by myocardial tomography imaging with exercise test. On the contrary the positivity of exercise ECG was only 63.8%. It was concluded that radionuclide myocardial tomography imaging was noninvasive and more sensitive and specific than the exercise ECG in detecting coronary heart disease.
