To determine the relative accuracy and efficiency of certain methods currently being used to assess bronchial architecture, results obtained with the respective techniques were compared with `true' values derived from planimetry on the bronchi of 30 subjects. Excellent comparative figures were obtained for each bronchial constituent measured (gland, cartilage, and bronchial wall areas) with the point count method and weighing paper cut-outs. The latter seemed to be the most economical from the standpoint of time saving. Results of Reid indices, acinar counts, and determinations of percentage mucous acini (applicable only to glandular structures) correlated poorly with planimetry.
为了确定目前用于评估支气管结构的某些方法的相对准确性和效率，将各技术所获得的结果与从30名受试者支气管的平面测量得出的“真实”值进行比较。用点计数法和称量纸样法对所测量的每个支气管成分（腺体、软骨和支气管壁面积）都获得了极佳的对比数据。从节省时间的角度来看，后者似乎最为经济。里德指数、腺泡计数以及黏液腺泡百分比测定（仅适用于腺体结构）的结果与平面测量结果相关性较差。
