Abstract

Preliminary results of a large-scale ROC study evaluating the diagnostic performance of digital hardcopy film and 2K X 2K softcopy display for pediatric chest radiographs are presented. The pediatric disease categories studied were pneumothorax, linear atelectasis, air bronchograms, and interstitial disease. Digital images were obtained directly from a computed radiography system. Results from the readings of 239 chest radiographs by 4 radiologists show no significant difference between viewing images on film and softcopy display for the disease categories pneumothorax and air bronchograms. A slight performance edge for softcopy was seen for the disease categories of interstitial disease and linear atelectasis.
