A method of determining the volume of emphysema in excised lungs is presented, with its validation. This method is based on macroscopic point counting using a perforated grid but only the holes (points) overlying emphysema need be counted to produce results within a percentage standard error of 5%. Application of the method shows that an adequate assessment of emphysema cannot be made from one lung slice alone, and that the amount of emphysema found in one lung cannot be used to predict the amount of emphysema in the other lung.
本文介绍了一种测定切除肺中肺气肿体积的方法及其验证过程。该方法基于使用穿孔网格进行宏观点数,但仅需计算覆盖肺气肿的孔(点)数,即可得出百分比标准误差在5%以内的结果。该方法的应用表明,仅从一个肺切片无法对肺气肿进行充分评估,且一个肺中发现的肺气肿量不能用于预测另一个肺中的肺气肿量。
