ASSESSMENT OF MYOCARDIAL VIABILITY BY THALLIUM REINJECTION REVASCULARIZAT

这项研究的目的是确定网络的作用和价值 单光子发射计算机断层扫描结合再注射技术 定量分析评价大鼠心肌活力 已知冠心病的患者。这将是决定谁是 将对干预做出最好的反应，并计划准确的类型 根据结果进行干预。 患者将在跑步机后进行标准SPECT铊检查 运动，但除此之外，第二次注射示踪剂将 在标准测试结束时给出。第三套 图像将在大约30分钟后执行。 再注射图像将与标准SPECT进行比较 确定是否有任何额外的优势 到第二次注射。

The purpose of this study is to determine the role and value of Spect Thallium imaging in conjunction with a reinjection technique and quantitative analysis to evaluate Viability of myocardium in patients with known CAD. This will be important in determining who will respond best to intervention as well as planning the exacttype of intervention based on the results. Patients will have standard Spect Thallium studies after treadmill exercise, but, in addition, a second injection of the tracer will be given at the conclusion of the standard test. A third set of images will be performed approximately 30 minutes later. The reinjection images will be compared to the standard Spect thallium images to determine if there is any additional advantage to this second injection.
