~(201)铊广泛用于心肌显象。但是,正常心肌摄取~(201)铊是不完全均匀的,这是使观察者视觉分析显象发生错误的主要因素。最近作者报告了用半定量的局部感兴趣区分析显象。本文对一组可疑冠心病病人的来加工的显象(Polaroid),扣除本底,增加对比度的 ~ (201) Thallium is widely used in myocardial imaging. However, normal myocardial uptake of ~ (201) thallium is not completely uniform, which is a major factor in the erroneous visualization of the observer. The authors report recently that semi-quantitative local regions of interest were used to analyze the images. This article on a group of suspicious patients with coronary heart disease to process the imaging (Polaroid), after subtracting the background to increase the contrast
