[High intensification film-screen systems in thoracic diagnosis. A clinical comparative study].
OBJECTIVE
The quality of chest images was evaluated for a conventional screen-film system, a new asymmetric screen-film system, and a new uv screen-film system.


METHODS
138 chest radiographs (69 p.a., 69 lateral) obtained with three different high intensification screen-film combinations were compared. Film density and film contrast were measured. Three readers graded the image quality according to 16 criteria.


RESULTS
The asymmetric film-screen combination Insight HC showed the lowest film contrast, the best exposure range, and a elevated film density in the mediastinal area. The asymmetric screen-film system was ranked by all three observers as being substantially better in image quality.


CONCLUSIONS
Compared to conventional screen-film systems, the new screen-film systems can improve the image quality of chest radiographs. Therefore, the new high intensification screen-film combinations can be used as a low cost alternative to the Amber technique and digital radiography.
