目的：提出一种基于计算机图像分析的方法，用于在纸上肺切片上测量肺气肿所占的宏观面积。方法：本研究基于改良Gough-Wentworth技术制备的69个肺切片的评估。比较了图像分析、点计数和面板分级方法的结果，以及图像分析和面板分级的可重复性。结果：图像分析结果与点计数结果差异无统计学意义（p=0.609），二次回归分析结果差异有统计学意义(r=0.96, p
Aim-To propose a computerised image analysis based method for measuring, on paper mounted lung sections, the area macroscopically occupied by emphysema.Methods-The study was based on the assessment of 69 lung sections prepared following a modified Gough-Wentworth technique. The results obtained from image analysis, point counting, and panel grading methods were compared, as was the repeatability of image analysis and panel grading.Results-The results from image analysis and from point counting were not significantly different (p=0.609) and significant quadratic regressions (r=0.96, p
