Technical innovation has recently resulted in the routine use of gated-SPECT in myocardial perfusion imaging. In the present work we compare estimates of left ventricular function (LV cavity) by gated-SPECT with those of conventional echocardiography in a group of 95 ischemic patients, 49 of whom had previous myocardial infarction. Kappa analysis showed correlation coefficients of 0.67 for global function in the whole group and of 0.68 in patients with MI, as well as of 0.56 in the anterior wall, and 0.55 in the inferior wall. With these data, we believe that the technique is useful and it adds to the conventional perfusion SPECT imaging. Also, it is conveniently validated against echocardiography in our hands.
技术创新最近使得门控单光子发射计算机断层扫描（gated-SPECT）在心肌灌注成像中得到常规应用。在本研究中，我们比较了95例缺血性患者通过门控SPECT对左心室功能（左心室腔）的评估结果与传统超声心动图的评估结果，其中49例患者曾有过心肌梗死。kappa分析显示，全组整体功能的相关系数为0.67，心肌梗死患者为0.68，前壁为0.56，下壁为0.55。基于这些数据，我们认为该技术是有用的，并且它为传统的灌注SPECT成像增添了内容。此外，在我们手中，它与超声心动图相比具有良好的验证效果。
