ASSESSMENT OF MYOCARDIAL VIABILITY BY THALLIUM REINJECTION REVASCULARIZAT

本研究的目的是确定SPECT的作用和价值 铊成像结合再注射技术和 定量分析评价急性心肌梗死患者心肌活力 已知CAD。这将是决定谁将做出最好反应的重要因素 干预以及根据以下情况规划确切的干预类型 结果。 患者将在跑步机后进行标准SPECT铊检查 运动，但除此之外，还将进行第二次示踪剂注射 在标准测试结束时。第三组图像将是 大约30分钟后执行。 再注射的图像将与标准的SPECT铊进行比较 图像来确定这一秒是否有任何额外的优势 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 exact type 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.
