RATIONALE AND OBJECTIVES:
The objective of this study was to compare reader accuracy and time efficiency between coronal reformats ofabdominopelvic computed tomography (CT) and axial images, by means of a visual search task.
MATERIALS AND METHODS:
In this experimental crossover study, a novel visual search task, containing targets placed on actual CT images, was constructed to assess reader performance on both planes. Six trials were shown to participants in each plane, at a fixed time of 0.5 seconds per slice. The task was presented to 43 junior doctors. On each trial, participants were assessed for accuracy and confidence in finding the target on a five-point scale. Statistical analysis was performed using the Wilcoxon signed rank test, and Fleiss kappa.
