目的 :研究 99m Tc- MIBI心肌断层显像心肌展开图显示法的应用。方法 :对 2 6例正常人、1 1 8例冠心病 (CHD) ,其中心肌缺血 (CHD- NMI) 92例 ,心肌梗塞 (CHD- MI) 2 6例进行 99m Tc-MIBI心肌断层显像 ,用一种新的半定量显示方法 -心肌展开图显示法进行分析判定 ,并与心肌断层一般显示法进行了比较。结果 :对 CHD阳性检出率为 93.2 % ,而一般显示法为 89.8% ;对 92例CHD- NMI组阳性检出展开图为 91 .3% ,而一般显示法为 88% ,对 CHD- MI组两者差别不大。结论 :半定量心肌展开图显示法可有效提高 CHD检测的重复性和检出率
Objective: To investigate the application of 99m Tc-MIBI myocardial imaging in myocardial imaging. Methods: Twenty-six patients with CHD were enrolled in this study. Twenty-six patients with coronary heart disease (CHD), 92 with myocardial ischemia (CHD-NMI) and 26 with myocardial infarction (CHD-MI) , With a new semi-quantitative display method - myocardial unfolding map analysis method to determine and compare with the general display of myocardial infarction. Results: The positive detection rate of CHD was 93.2%, while the general display method was 89.8%. The positive detection of 92 cases of CHD-NMI group was 91.3%, while the general display method was 88% Little difference between the two groups. Conclusion: Semi-quantitative myocardial unfolding map display can effectively improve the repeatability and detection rate of CHD detection
