Smokers have twice as many lesions as nonsmokers. No significant difference was shown between patients with different levels of asbestos exposure. On the whole, 9.4% of the images could be related to asbestos exposure. Findings were incidental in 87.6% of cases. They were considered clinically significant in 6 cases.Conclusion: The diagnosis of few asbestos related lesions and conversely a large amount of incidental findings raises the question of the benefits of a large scale screening. Indeed, the study highlighted more of a personal, than a medical benefit.
