Window settings in the application of pneumoconiosis digital radiography / 中华劳动卫生职业病杂志

ABSTRACT

Objective@#To explore window settings technology in the digital radiography of pneumoconiosis, and to improve the quality of the digital chest radiographs.@*Methods@#25 female workers in a asbestos product processing enterprise were examined with high-kV and DR chest radiographies on same day. Consistency of pneumoconiosis diagnosis@*results@#were assessed. Results In the 75 groups of radiograph quality results, there are 62 groups that need to be processed window in order to make the correct diagnosis. The crude agreement among two chest radiographs was 28% for the profusion of small opacities and 76% for the classification of pneumoconiosis, the weighted kappa value (κ) was 0.33 (95%CI 0.12-0.54) and 0.67 (95%CI 0.42-0.92) .@*Conclusions@#window settings technology can display different parts of chest and make DR chest radiograph to meeting the requirements of chest radiograph quality for pneumoconiosis.
