Asbestos has been widely sued in for more than 40 years. Asbestos is a collective term for some metamorphic. Fibrous, mineral silicates. Most of the asbestos was used for brake lining, con-strction materials, and insulation. Asbestos-related disorders can be divided into malignant and nonmalignant diseases. The nonmalignant diseases include asbestosis, pleural effusion, pleural thickening, pleural calcifications or plaque, and skin corns. The malignant disorders related to asbestos exposure include lung cancer, pleural or peritoneal mesothelioma, stomach cancer and laryngeal cancer. Although asbestos workers in Taiwan have been ling-term and heavily exposed to asbestos, only three cases of asbestosis were reported in the previous literatures. None of cancer has been reported to be associated with asbestos exposure. The possible reason for the underestimation of the prevalence of asbestosis may be due to underdetection by regular chest radiography with limited resolution. Another possible reason was due to ignorance of radiographic reader without detailed occupational exposure histoy. The radiological examinations used to detect asbestos-related disorders are chest X ray com-puted tomography and high resolution computed tomography. Chest film is most common method. The findings of chest films was classified by ILO, including plaque, thickening an profusion. In CT and GRCT, no uniform classification was used. Pleural plaques, effusions, diffuse pleural thickening ,fibrotic mass and asbestosis were recognized as the common manifestations of asbestos-related disease in CT scan, As CT scan, the findings of asbestos-related in HRCT were still controversial. Five findings (curvilinear subpleural lines, thickened interstitial short lines, suabpleural dependent density, parenchymal bands, and honeyconmbing)were noted in many studies, Because of greater sensitivities and specificity, HRCT is a better selection in diagnosis and early detection of asbestos-related disease.
