目的：通过与冠状动脉造影比较，评价９９ｍＴｃ－ Ｔｅｔｒｏｆｏｓｍｉｎ心肌灌注显像在冠心病诊断中的价值。方法：对 ２４例受检者（ＣＨＤ１４例，非 ＣＨＤ１０例）进行静息和运动负荷状态下的９９ｍＴｃ－ Ｔｅｔｒｏｆｏｓｍｉｎ心肌 ＳＰＥＣＴ显像，同期也行冠状动脉造影。结果：以冠状动脉造影为金标准，９９ｍＴｃ－Ｔｅｔｒｏｆｏｓｍｉｎ心肌 ＳＰＥＣＴ显像诊断冠心病的灵敏度、特异性和准确率分别为９２．３％，６０％和７８．３％。结论：９９ｍＴｃ－Ｔｅｔｒｏｆｏｓｍｉｎ心肌灌注显像在冠心病诊断中具有较高的临床价值。
Objective: To evaluate the value of 99mTc-Tetrofosmin myocardial perfusion imaging in the diagnosis of coronary heart disease by comparing with coronary angiography. Methods: SPECT imaging of 99mTc-Tetrofosmin under rest and exercise load was performed on 24 subjects (CHD, non-CHD, 10 cases) and coronary angiography at the same time. Results: The sensitivity, specificity and accuracy of 99mTc-Tetrofosmin myocardial SPECT imaging in diagnosis of coronary heart disease were 92.3%, 60% and 78.3%, respectively, using coronary angiography as the gold standard. Conclusion: 99mTc-Tetrofosmin myocardial perfusion imaging has high clinical value in the diagnosis of coronary heart disease.
