^（99m）Tc－MIBI心肌灌注断层显像的临床应用

THE CLINICAL APPLICATION OF SPECT MYOCARDIAL PERFUSION IMAGING ^(99m)Tc-MIBI

本文报道了１２６例￣（９９ｍ）Ｔｃ－ＭＩＢＩ，心肌灌注断层显像，并与ＥＣＧ作了对比。结果表明，Ｔｃ－ＭＩＢＩ缺血性心脏病诊断的灵敏度、特异性、准确性、阳性预测率分别为８９．７％、８７．２％、８８．９％和９３．９％。其灵敏度明显高于ＥＣＧ（５０．６％，Ｐ＜０．０１）。作者认为心肌灌注断层显像为心肌缺血的首选方法，但并非特异性方法。

In this paper,126 cases were examined by SPECT myocardialperfusion imafinerrs with ￣(99m)Tc-MIBI. The results were compared with theECG,and showed that the sensitivity, specificity,accuracy, positivity prediction rate of SPECT in diagnosing ischemic heart disease were 89.7%,87.2%, 88.7%and 93.9% respectively,The sensitivity of SPSCT was hig-her than that of ECG(50.6%,P<0.01).We considered that SPECT myo-cardial perfusion imaging to be the first method selected in diagnosingmyocardial ischemia.
