尘斑型尘肺的定量诊断方法

为了解决尘肺病理诊断工作中人为因素的影响问题，作者采用计算机模拟技术，绘制了尘斑型尘肺肺切面的模拟图，并应用体视学定量分析的方法提出了尘斑型尘肺分期的体密度划分标准，对应于尘斑面积为１００％、７５％和５０％的尘斑体密度分别为４１．４、３１．Ｏ和２０．７。经用《尘肺病理诊断标准》提供的标准片进行检验，得到了满意的效果。作者建议在实际测量时使用小格边长为５ｍｍ的方格测试板。

Quantitative Diagnosis of Dust-macule Type Pneumoconiosis

imulated diagrams of lung sections of dust-macule type pneumoconiosis were plotted with computer simulation techniques and classification criteria for dust-macule volume density were formulated with stereologic quantitative analysis to differentiate the effects of artificial factors in pathological diagnosis of pneumoconiosis, Areas of dust-macule of 100%, 75%and 50%corresponded to 41.4,31.0 and 20.7 in dast-macule density,respectively. The pathological diagnostic criteria for pneumoconiosis were evalu-ated by standardized chest X-ray film with a satisfactory result.It is suggested a squared test grid with a length of 5 mm in each sides of the small checks be used in practice.
