Myocardial imaging with 99mTc-MIBI were performed in 56 cases with myocardial infarctioa and 38 cases without infarction. The result showed that the sensitivity

specificity and ac-ouracy were 92.86%

100% and 95.74% respectively. In comparison with the findings of ECG

the size and location of infarcted areas shown by γ-camera are more accurate

can be directly perceived and can give a whole picture sense of entirety. The features of dilation myocardiopathy are obvious dilation of heart and generalized thinning of the myocardial wall

but without localized defect of perfusion.
