Abstract

Radiological diagnoses include tasks of detection and interpretation. Information from previous studies of observer performance was used to investigate the correlation between the detection and characterization of imaging features for five groups of observers who reviewed 300 posteroanterior (PA) chest images using each of the following modes: conventional films, digitized images displayed on laser-printed films, and high-resolution soft display with and without edge enhancement. Feature detection tasks for each image included the presence or absence of septal lines and nodules; interpretation tasks included the diagnosis of interstitial disease and the characterization of nodules as benign or malignant. In this study, edge enhancement resulted in an increase of both true- and false-positive detection of septal lines. Although limited by the small number of pathologically classified nodules (31), there was no significant correlation between a reader's ability to detect nodules and characterize them as benign or malignant, regardless of the mode of image presentation.
