Abstract

<abstract abstract-type="main"> <title>Abstract</title> <sec id="crj12063-sec-0001" sec-type="section"> <title>Introduction</title> <p>Welder's lung disease originated from a mixed exposure to different kinds of metals and chemicals from welding fumes. Because of these various harmful effects, irreversible morphological changes may occur in all parts of the respiratory tract, airways and lung parenchyma. Parenchymal changes are the main lesions that define the severity of exposure. The grade of these lesions is the main criteria for compensation claims and the clinical threshold for the occupational health physician's decision making of work change in order to protect the worker's health. In this study, our aim was to compare the diagnostic performance of chest X‐ray (CXR) and high‐resolution computed tomography (HRCT) for welders' lung disease.</p> </sec> <sec id="crj12063-sec-0002" sec-type="section"> <title>Objectives</title> <p>Seventy‐four male welders aged between 25 and 55 years were enrolled to this study.</p> </sec> <sec id="crj12063-sec-0003" sec-type="section"> <title>Methods</title> <p>Clinical diagnoses were compared by CXR and HRCT.

The mean duration of exposure was 18.9 years.
