Abstract

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.

摘要

本文展示了关于微机与专家在通过X线胸片诊断尘肺病方面的一致性结果。在一组200张胸片上，比较了计算机和五位专家做出的诊断；在100张胸片中，正常/异常的一致性率为83.5%，四类密集度的一致性率为73.0%，四类尘肺病的一致性率为70.5%。在100张胸片中，计算机与基层会诊组的一致性率分别为86.0%、82.0%和63.0%。在300张用于筛查尘肺病的胸片中，计算机与专家的一致性率为89.3%。结果表明，计算机自动诊断更接近专家的诊断。
