Abstract
The aim of this research is to analyze artifacts in dual-energy chest radiography: their appearance and how to eliminate them. A total of 252 patients were examined in random order by using dual-energy radiography. As a result, 756 images were analyzed. This review describes the most important and most prevalent of them, including motion artifacts - 58 (41,4%), quantum noise – 55 (39,2%) and decreasing the suppression of bony elements on soft-tissue-selective images – 27 (19,3%). The main reason of dual-energy chest radiography artifacts is incorrect image reconstruction parameters.
