  • Title: [High intensification film-screen systems in thoracic diagnosis. A clinical comparative study].
    Author: Schäfer CB, Sokiranski R, Claussen CD.
    Journal: Aktuelle Radiol; 1995 Nov; 5(6):389-93. PubMed ID: 8580141.
    Abstract:
    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. MATERIALS AND 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. CONCLUSION: 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.
