Myocardial 201Tl emission computed tomography was performed on 25 normal subjects and 27 patients with angiographically significant coronary artery disease. A semi-automatic computer program was designed to define the left ventricular myocardial volume in all short axis sections. Within this volume the relative mean myocardial pixel count was calculated. This parameter was found to separate the 2 patient groups with a sensitivity of at least 81% at a specificity of 100%.
对25名正常受试者和27名经血管造影证实患有严重冠状动脉疾病的患者进行了心肌铊-201发射计算机断层扫描。设计了一个半自动计算机程序来确定所有短轴切片中的左心室心肌体积。在该体积内计算相对平均心肌像素计数。发现该参数能够区分这两组患者，在特异性为100%时，敏感性至少为81%。
