ILO International Classification of Radiographs of Pneumoconioses

The ILO International Classification of Radiographs of Pneumoconioses provides a means for describing and recording systematically the radiographic abnormalities in the chest provoked by the inhalation of dusts. It is used to describe radiographic abnormalities that occur in any type of pneumoconiosis and is designed for classifying only the appearances seen on postero-anterior chest radiographs.

The object of the ILO Classification is to codify the radiographic abnormalities of the pneumoconioses in a simple, reproducible manner. The ILO Classification is used internationally for epidemiological research, for screening and surveillance of those in dusty occupations, and for clinical purposes.

The ILO Classification consists of Guidelines for the use of the ILO International Classification of Radiographs of Pneumoconioses along with a set of standard radiographs. The Guidelines is a technical publication designed to standardize classification methods and facilitate international comparisons of pneumoconiosis statistics and research reports.

The ILO is currently in the final phase of updating the ILO International Classification of Radiographs of Pneumoconiosis, this is, the Guidelines together with a set of 23 digitally acquired standard images. The intention is to publish the updated version of the ILO Classification on the ILO website.
