Abstract

A receiver operating characteristic (ROC) experiment is used to compare the diagnostic performance of analog film to digital hardcopy and compressed hardcopy. The compression is done using a full-frame bit-allocation algorithm carried through on a custom designed board residing on a SUN computer bus. Image set included thirthy-one radiographs with septal lines (n=18) and/or parenchymal nodules (n=14), with six radiographs that had neither abnormality. Six radiologists viewed the image set under each modality. There is no statistically significant difference between the three modalities.
