Abstract: 

Pneumoconiosis is a chronic and irreversible lung disease. Inhalation" inorganic dust particles over a long period of time is the cause of this disease. Dust particles < 5 Micron enter the alveolar sac and are removed from the sac by macro phages . Irritation of the interestitiallung tissue leads to fibrosis. In this study, 735 workers (all male) employed at Siman Sepahan were asked to Fill out a questionnaire and underwent chest X-Rays (Antero - posterior & lateral views) of which 110 of them were dditionally C.T scanned. 70% of the X-rays were normal. while 30% had abnormal findings. Abnormal chest X-ray and spirometry findings had a direct relationship with age. and therefore about half of the workers in the 45-54 age group had symptoms of the disease. and 41.6% had an abnormal chest X-ray. On comparison of chest X - Ray findings and CT scan findings, in patients with abnormal spirometry findings, it was realized that the positive predictive value of chest X- Rays in relation to CT Scan was 100% while the negative predictive value was 7.4% . Therefore. a positive chest X-ray finding has a more diagnostic value than a negative one. In other terms. a negative chest X-Ray finding does not rule out Pneumoconiosis. It is therefore suggested that suspected cases of pnuemoconiosis should" undergo a CT scan irrespective of the chest X-Ray findings.
