The self-study syllabus provides an overview of the clinical and pathologic basis of selected occupational lung diseases. It also provides radiographs with explanations and answer keys as outlined below.

I. ILO International Classification of Radiographs of Pneumoconioses

The ILO Classification provides a means for systematically describing and recording  radiographic abnormalities in the chest after inhaling dust. 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 purpose of the ILO Classification is to codify radiographic abnormalities of the pneumoconioses in a simple, reproducible manner. The ILO Classification is used internationally for:

  • Epidemiological research
  • Screening and surveillance of workers in dusty occupations
  • For clinical purposes

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