An evaluation was presented that covered 59 cases of pneumoconiosis (20 silicosis and 39 asbestosis). The diagnosis of pneumoconiosis was made in the light of several elements including exposure time, clinical data, pulmonary function test, bronchoalveolar lavage, scintigraphy, medical imagery and pulmonary biopsy. Most of the diagnoses were made on epidemiological and clinical data and 28 on the results of bronchoalveolar flush. Tomodensitometry revealed the parenchymal lesions better than the standard plate. Thus, out of seven patients in category-1 of the International Labor Office (ILO) classification, only one demonstrated light disease with tomodensitometry. The six others had moderate disease. Out of ten cases in category-2 ILO, seven revealed severe disease with tomodensitometry and only three demonstrated moderate disease. The possibilities that tomodensitometry offered for the evaluation of pneumoconioses were far superior to that of the standard plate which, nevertheless, remained very useful for monitoring these lesions. The authors conclude that the ILO classification will have to be revised or completed in the light of tomodensitometry.
