The visual interpretation of Thallium-201 myocardial images is made more difficult by nonhomogeneity of myocardial tracer uptake in normal studies. To increase the objectivity of the study, the variation in count density in different myocardial areas has been calculated using a computer regions of interest technique in 14 healthy, young subjects following intravenous injection of the radionuclide at rest and in 10 after injection during maximal exercise. The "normal ranges" for regional Thallium-201 uptake so obtained are presented and discussed.
在正常研究中，心肌示踪剂摄取的不均匀性使得铊-201心肌图像的视觉解读变得更加困难。为提高研究的客观性，在14名健康年轻受试者静息状态下静脉注射放射性核素后，以及在10名受试者最大运动后注射放射性核素后，使用计算机感兴趣区技术计算了不同心肌区域的计数密度变化。本文展示并讨论了由此获得的区域铊-201摄取的“正常范围”。
