ASSESSMENT OF MYOCARDIAL VIABILITY BY THALLIUM REINJECTION REVASCULARIZAT

本研究的目的是确定 SPECT铊成像结合再注射技术 定量分析评价心肌活力 已知CAD的患者。这将是重要的，在确定谁 将最好地应对干预以及规划的确切类型 根据结果进行干预。 患者将在跑步机后进行标准的Spect铊研究 运动，但是，此外，第二次注射示踪剂将 在标准测试结束时给出。 第三组 将在大约30分钟后进行成像。 再注入图像将与标准Spect进行比较 铊图像，以确定是否有任何额外的优势， 这第二次注射。

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.
