| Research Abstract |
In a comparison of film-screen image and FCR, the findings that FCR was inferior to a film-screen image was not observed. The frequency that FCR was superior to filmpscreen image by +1 point or +2 points was 31% of a large nodular shadow, 40% of an accompanying shadow with nodule, 67% of a small nodular shadow, and 43% of the lymph node shadow in the hilum of the lung or mediastinum.
In large nodular shadows which were the most frquent abnormality, score +1 or +2 were observed in 43% of adenocarcinoma and 26% of squamous cell cancer.
Detectability of FCR for nodular lesions was high in adenocarcinoma compared to squamous cell cancer, although it was not a statistical significance.
Conclusion. The diagnostic performance of the new dual side reading system of FCR is superior to that of the conventional screen-film system for nodular lesions of the lung caner.
