尘肺X线片微机自动诊断与专家诊断的对照研究

Comparing the Diagnoses of Pneumoconiosis Made by Computer and Experts from X ray Films

报告了尘肺Ｘ线片微机诊断与专家诊断的对照验证结果。根据２００张Ｘ线片的结果比较，对应于有无尘肺、四级密集度和四级尘肺三种不同分类方法，诊断符合率分别为８３５％，７３０％和７０５％。通过１００张Ｘ线片与基层诊断组的结果比较，对应的诊断符合率分别为８６０％，８２０％和６３０％。由３００张Ｘ线片进行尘肺普查筛选，与专家筛选的符合率达８９３％。结果表明，微机自动诊断符合率接近专家诊断水平。

The results on the agreement between microcomputer and experts for the diagnosis of pneumoconiosis from X ray films are presented in this paper.On a set of 200 films,the diagnoses made by the computer and by five experts were compared;From 100 films,the agreement rates were 83.5% for the normal/abnormal,73.0% for the four categories of profusion and 70.5% for the four categories of pneumoconiosis.From 100 films,the rates of agreament between the computer and the basic level consultation group were 86.0%,82 0% and 63.0% respectively.From 300 films for screening pneumoconiosis,the rate of agreement between the computer and the experts was 89.3%.The results demonstrate that the automatic diagnosis by computer is closer to the diagnosis made by experts.
