Objective:
The aims of the study were to develop and evaluate "eTóraxLaboral," an intelligent platform for detecting signs of pneumoconiosis in chest radiographs and to assess its predictive capacity.
Methods:
A retrospective analysis of 2300 randomly selected chest radiographs was performed. Sensitivity, specificity, false positive/negative rates, predictive values, likelihood ratios, efficiency, error rate, and area under the receiver operating characteristic curve were evaluated. A Fagan nomogram and ROC curve analysis were included.
Results:
"eTóraxLaboral" demonstrated high sensitivity to signs of pneumoconiosis (LR+ 23, LR- 0.2). A slight tendency toward a higher number of false positives was observed, possibly due to the superposition of anatomical elements and increased lung markings. False negatives were less common, often misinterpreting pneumoconiotic opacities as consolidation-type findings.
Conclusions:
"eTóraxLaboral" facilitates early pneumoconiosis detection, providing crucial diagnostic support for healthcare workers in Chile and other developed or developing nations.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
