The distribution of 201thallium (Tl) in the myocardium has been studied by the new technique of emission tomography, and compared with standard gamma camera images in 5 patients. Tomographic imaging was carried out using a dual-detector scanner operated under the single-photon technique. Initial results have been promising, with visualisation of resting perfusion defects in patients with recent infarction and those with ventricular aneurysms. Emission tomography has also been performed at exercise, and has shown tracer deficits in the distribution of significant coronary stenoses. This new approach to myocardial perfusion scintigraphy may lead to improved sensitivity for detecting apical and inferior wall abnormalities by providing depth information not available from a conventional two-dimensional image.
采用发射断层扫描新技术研究了201铊（Tl）在心肌中的分布，并与5例患者的标准γ相机图像进行了比较。断层成像使用在单光子技术下操作的双探测器扫描仪进行。初步结果很有前景，可显示近期梗死患者和室壁瘤患者静息灌注缺损情况。还在运动时进行了发射断层扫描，结果显示在明显冠状动脉狭窄分布区域存在示踪剂缺失。这种心肌灌注闪烁造影的新方法通过提供传统二维图像所没有的深度信息，可能会提高检测心尖和下壁异常的敏感性。
