Brief summary
This study is a comparative study investigating how ILO chest x-ray compares to low dose high resolution computed tomography (LD HRCT) for early diagnosis of occupational lung disease. As part of this study participants will be asked to undergo a LD HRCT scan, which is new technology using very low levels of radiation. HRCT scans are better at diagnosing early stage of occupational lung diseases than chest radiography. This study will answer the question about whether the low radiation dose HRCT scan used in this study picks up more early stage lung diseases such as black lung, emphysema and silicosis. No Australian evidence has been collected to demonstrate the use the use of LD HRCT in the screening of occupational lung diseases.
Interventions
The research intervention is a single low dose (LD) high resolution computed tomography (HRCT) scan (non-contrast). The LD HRCT scan will be done in a fully accredited imaging clinic by an accredited radiologist. There is no dye injection, and no special preparation required. The scan is performed within a CT scan machine, and takes less than 15 minutes. The participant will be asked to breathe in and out for different scan images. The CT scan can be performed on the same day as the workers standard care International Labour Organisation chest x-ray (ILO CXR) or within 3 months of their ILO CXR (to fulfill inclusion criteria). No further radiological and/or clinical investigation will be undertaken as part of this study.
