The purpose of this study was to compare direct (analog) viewing of thoracic radiographs with digitized images obtained with a radiographic scanner and seven digital cameras for detection of pulmonary nodules. Direct viewing of the analog radiographs was significantly better than all digitized methods ( P <0.01). Significant variations exist between the radiographic scanner and the digital cameras. The scanner (Kodak LS75) was significantly better than the Kodak DC 4800 and the Sony DSC‐707 cameras ( P <0.05). The Nikon 995, Canon EOS‐D30, and Ricoh i500 were significantly better than the Sony DSC‐707 ( P <0.05). There was no significant difference between the Kodak DC 3800, Kodak DC 4800, and the Sony DSC‐707. For pairwise comparison of raters (when evaluating the radiographs individually compared with the consensus), the raters matched the consensus rating from 85% to 92% with no significant difference between raters.
