80例胸痛患者门控心肌显像的临床分析

目的进一步探讨负荷、静息门控心肌灌注显像在临床主诉胸痛、胸闷而疑诊冠心病患者中的临床应用。方法对80例有胸痛、胸闷不适主诉，临床疑诊冠心病的患者，行负荷及静息心肌灌注显像，分析显像的图像特点及对门控图像进行定量分析获得左心室射血分数（LVEF）。LVEF分为3组对比：①显像阳性与阴性的负荷比较；②显像阳性与阴性的静息比较；③所有负荷和所有静息的对比。结果对照冠脉造影结果，静息及负荷门控心肌灌注显像敏感性分别为81．1％和91．1％，特异性85．2％和88．9％，各组间LVEF差异无统计学意义。结论负荷或静息心肌灌注显像对胸痛、胸闷患者在冠心病诊断临床应用方面有很好价值；定量分析软件所得心功能指标有一定参考作用，但是尚不能作为诊断标准。

The clinic analysis of 80 examples of 99m Tc-MIBI Gated SPECT

Objective To study the diagnostic value of Rest-adenosine stress 99mTc-MIBI G-MPI in suspected coronary artery disease (CAD) patients with chest pain or distress. Methods There 80 suspected coronary artery disease patients with chest pain or dis-tress, received Rest - adenosine stress 99mTc-MIBIG-MPI and coronary artery angiography, the results were compared . Results The sensitivity of rest-adenosine stress G-MPI were 81.1% and 91.1% respectively, and the specificity of MPI and G-MPI were 85.2% and 88.9% respectively. Conclusion Rest-adenosine stress 99mTc-MIBI G-MPI has high specificity in detection of coronary artery dis-ease.
