ABSTRACT
OBJECTIVE:
The purpose of this study was to compare a new digital chest radiography system that uses amorphous selenium as the X-ray detector with conventional radiography for the visualization of various anatomic regions of the chest as a first phase of testing image quality. MATERIALS ANDMETHODS:
Six observers analyzed pairs of posteroanterior chest radiographs of 40 patients. One radiograph in each pair was obtained with a conventional chest film changer, and the other was obtained with the digital selenium chest radiography system. Each observer rated the visibility and the radiographic quality of 12 different anatomic regions.RESULTS:
The observers rated visualization obtained with the digital system as better than that obtained with the conventional system in four regions (right lower lobe, upper lobes, ribs, and soft tissue), as better than or equal to that obtained with the conventional system in four regions (retrocardiac, retrodiaphragmatic, hilum, and upper mediastinum), and as equal to that obtained with the conventional system in four regions (horizontal fissure, carina, azygoesophageal recess, and thoracic spine). Some observers had a strong preference for the digital images, whereas others showed no preference. The conventional system was not ranked high for any region (2880 observations, p < .01, sign test).CONCLUSION:
The digital selenium chest radiography system performs well in a clinical setting, providing visualization of anatomic structures that is better than or at least equal to that provided by standard screen-film images.
