Abstract:
Objective:To explore the feasibility of soft copy image of chest digital radiography (DR SC) in pneumoconiosis diagnosis by observing the reading effect of DR SC and comparing it with high kV film-screen chest radiography (FSR HkV) . To provide a basis for the establishment of a regional information network platform for pneumoconiosis diagnosis. Methods:A total of 119 miners who were exposed to silica dust and engaged in copper or lead-zinc mining were collected by the Third People's Hospital of Yunnan from October 2017 to August 2019. The pulmonary X-ray findings of DRSC and FSR HkV in each case were independently judged and diagnosed by three experienced diagnostic physicians, and the final decision was made according to the consensus of most doctors. The consistency of the two imaging methods was analyzed by observing the main small opacity shape, the overall density, the range of distribution, the aggregation of the small opacity and the big opacity, and the diagnosis stage. Results:there were 118 males and 1 female with an average age of 46.21 years. Average exposure time 7.38 years. The pulmonary X-ray findings of 113 cases with two imaging methods were mainly the round small opacity of p,q and r,but the reticular irregular opacity were not prominent, Only one case of FSR HkV judgment p shape and DR SC judgment q shape were observed, The coincidence rate was 99.12% (112/113) . huger opacity were observed in the other 6 cases. The coincidence rate was 95.51% (4/89) between pneumoconiosis-free and stageⅠ, and there was no significant difference between stageⅡand stage Ⅲ (30/30, P>0.05) . Conclusion:The x-ray findings of Silicosis with small round shadow in lung can be used by DR SC in diagnosis and staging.
