The aims of this study were to test inter-observer and intraobserver agreement in the diagnosis of silicosis using conventional chest radiography and AMBER. One hundred and fifteen patients underwent chest x-rays and AMBER for the diagnosis of silicosis. Five readers blindly and independently evaluated the radiograms with standard ILO/UC classification scales. Reproducibility was assessed using ANOVA repeated measurements methods. AMBER showed a better technical quality of radiograms than conventional chest x-rays; interobserver reproducibility was high and similar (R = 0.75); intraobserver agreement between chest x-rays and AMBER was high ranging from 0.62 to 0.86 for the 5 readers. Notwithstanding the absence of standards for profusion classification, the interobserver reproducibility with AMBER was similar to that obtained with chest x-rays. Moreover, the intraobserver agreement in profusion scoring between AMBER and chest radiography was high, suggesting that AMBER and chest radiography provided similar information in the evaluation of silicosis.

Abstract

The aims of this study were to test inter-observer and intraobserver agreement in the diagnosis of silicosis using conventional chest radiography and AMBER. One hundred and fifteen patients underwent chest x-rays and AMBER for the diagnosis of silicosis. Five readers blindly and independently evaluated the radiograms with standard ILO/UC classification scales. Reproducibility was assessed using ANOVA repeated measurements methods. AMBER showed a better technical quality of radiograms than conventional chest x-rays; interobserver reproducibility was high and similar (R = 0.75); intraobserver agreement between chest x-rays and AMBER was high ranging from 0.62 to 0.86 for the 5 readers. Notwithstanding the absence of standards for profusion classification, the interobserver reproducibility with AMBER was similar to that obtained with chest x-rays. Moreover, the intraobserver agreement in profusion scoring between AMBER and chest radiography was high, suggesting that AMBER and chest radiography provided similar information in the evaluation of silicosis.
