The standard films represent different types and severity of abnormalities and are used for comparison to subject films during the classification process. The object of the classification is to codify the classificatikn abnormalities of pneumoconioses in a simple, reproducible manner.

The flattening of the diaphragm should be recorded by an additional symbol since it is a very important feature in asbestos exposure. Am J Radiol; Summary of details of classification. The purpose is to describe pneumoconioss codify radiographic abnormalities of pneumoconioses in a simple, systematic, and reproducible manner. The 22 standard radiographs have been selected after international trials, in such a way as to illustrate the mid-categories standards of profusion of small opacities and to give examples of category A, B and C standards for large opacities.

Also shows vascular pattern, but not as clearly as example 1. Discussion in particular at the Seventh International Pneumoconioses Conference, held in Pittsburgh inindicated the need for improvement of some parts of the classification, in particular those concerning pleural changes. It retained the principle of former classifications and The value of the Classification depends critically on the consistency with which users apply the Classificatino published by the ILO and the standard radiographs that accompany those Guidelines.

The most important condition for using this classificatlon of classification with full value from a scientific and ethical point of view is to read, at all times, films to be classified by systematically referring to the 22 standard films provided in the ILO International Classification set of standard films.

Vascular pattern is well illustrated.

pneumoclniosis This page was last edited on 9 Septemberat The maximum width usually occurs at the inner margin of the rib shadow at its outermost point. This is why the International Labour Office ILOthe World Health Organization WHO and many national institutes for occupational health and safety continue their fight against these diseases and to propose sustainable programmes for preventing them.

Part of this programme is based on medical surveillance which includes the reading of thoracic radiographs to help diagnose this pneumoconiosis.

The film sets were new to coincide with the ILO Guidelines; the digital set is new and coincides with the Guidelines.

Poor, with some technical defect but still acceptable for classification purposes. Classification Scheme The Classification System includes the Guidelines and two sets of standard films. They were identified according to the six zones—upper, middle and lower, of both right and left lungs. Tools and Approaches Part V.

Calcified and uncalcified pleural thickening present face on, is of indeterminate width, and extent 2. Acceptable, with no technical defect likely to impair classification of the radiograph of pneumoconiosis.

In the present manifestation of the ILO system, the reader is raidographs asked to grade film quality. It is also used for describing and recording, in a systematic way, part of the information needed for assessing compensation.

CHEST RADIOGRAPHY

The description of standard radiographs is given in table 1. The presence of a ov number of another shape and size is recorded after the oblique stroke. Sincethe International Labour Organization [1] has been a specialized agency of the United Nationswith objectives including establishing and overseeing international labor standards and labor rights.

Definition of pleura is slightly imperfect. Whether plaques are classified or not should be merely indicated by a symbol. For pleural thickening seen along the lateral chest wall the measurement of maximum width is made from the inner line of the chest wall to the inner margin of the shadow seen most sharply at the parenchymal-pleural boundary.
