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， 定量分析评价心肌梗死患者的心肌活力 已知CAD 这将是重要的，以确定谁将作出最佳反应， 干预以及规划干预的确切类型， 结果。 患者将在跑步机后进行标准的Spect铊研究 运动，但除此之外，将给予第二次注射示踪剂 在标准测试结束时。 第三组图像将是 大约30分钟后进行。 将再注入图像与标准Spect铊进行比较 图像，以确定是否有任何额外的优势，这第二 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.
