[Comparing the diagnoses of pneumoconiosis made by computer and experts from X-ray films]

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.
