Resum

Silicosis is a disease without treatment. The surveillance program for workers exposed to silica is designed to detect as early as possible by a chest radiograph. Despite its fundamental role, it suffers from a great technique and interpretation variability. To reduce these phenomena, the ILO created a classification system widely used in Chile and the world. This was based on analog radiography, which has been replaced by the same analog set, digitized. While the ILO permits the use of this new type of image it indicates that the pattern comparison must remain analog. Many studies have shown that it is best to use digital comparison patterns. The objective of this work was to generate a set of digital x-rays representing the central profusion of round opacities of ILO classification system. From a universe of 32,826 x-rays of patients exposed to silica, 252 films, of which 54 were reported for 3 accredited readers, selected 8 cases that had pure round opacities of different profusions was obtained, which are proposed as digital pattern for Chile.
