||The objective of this study was to clarify the indications for high-resolution computed tomography (HRCT) in the surveillance of workers heavily-exposed to asbestos. A group of 627 workers known to have been heavily-exposed to asbestos were screened and HRCT findings were classified and divided in two groups: pulmonary fibrosis (n = 86) and no fibrosis (n = 541). Most of the detected fibrosis cases were mild. The magnitude of asbestos exposure showed an unexpected inverse relation with fibrosis. In multivariate analyses, age, lung function and diffusing capacity were associated with HRCT fibrosis, but asbestos exposure was not. Asbestosis seems to be characterized by mild fibrosis today even in heavily exposed workers. Implications of these and other findings are discussed.
