AB  - AIM: To assess whether low voltage chest computed tomography (CT) can be used to 
      successfully diagnose disease in patients with asbestos exposure. MATERIALS AND
      METHODS: Fifty-six former employees of the shipbuilding industry, who were
      candidates to receive a standard-dose chest CT due to their occupational exposure
      to asbestos, underwent a routine CT. Immediately after this initial CT, they
      underwent a second acquisition using low-dose chest CT parameters, based on a low
      potential (80 kV) and limited tube current. The findings of the two CT protocols 
      were compared based on typical diseases associated with asbestos exposure. The
      kappa coefficient for each parameter and for an overall rating (grouping them
      based on mediastinal, pleural, and pulmonary findings) were calculated in order
      to test for correlations between the two protocols. RESULTS: A good correlation
      between routine and low-dose CT was demonstrated for most parameters with a mean 
      radiation dose reduction of up to 83% of the effective dose based on the
      dose-length product between protocols. CONCLUSIONS: Low-dose chest CT, based on a
      limited tube potential, is useful for patients with an asbestos exposure
      background. Low-dose chest CT can be successfully used to minimise the radiation 
      dose received by patients, as this protocol produced an estimated mean effective 
      dose similar to that of an abdominal or pelvis plain film.
