In this paper a new method of using 81mKr for the measurement of specific absolute regional lung ventilation is described. Experimental data suitable for the calculation of quantitative regional ventilation are provided using an adequate respiratory system for 81mKr dosage and a scintillation gamma camera interfaced to a digital computer. A simple mathematical lung model for the inhalation of 81mKr is used to determine the specific ventilation and the parameters proportional to the ventilation for the whole lung and different lung regions in patients and in healthy subjects. The lung count rate for a given region correlated well with the ventilation of that region. Clinical examples are given and discussed.
本文描述了一种使用81m氪测量特定绝对局部肺通气的新方法。通过一个适用于81m氪剂量的呼吸系统和一台与数字计算机相连的闪烁γ相机，提供了适合计算定量局部通气的实验数据。使用一个简单的81m氪吸入肺部数学模型来确定患者和健康受试者全肺及不同肺区域的特定通气量和与通气量成比例的参数。给定区域的肺计数率与该区域的通气量密切相关。文中给出并讨论了临床实例。
