Accuracy and efficiency of radiologists reporting CT studies from a multiscreen electronic workstation

This paper describes a limited picture archiving communication system linking, a via fiber optic cable, two computed tomographic (CT) scanners, and a double-screen (1,000-line monitors) display station with a 600-megabyte image memory evaluated for accuracy and efficiency in the generation of a radiology report. Twenty preselected CT studies (an average of 30 images per study, ten with prior examination for comparison) in cases with pathologically or clinically proved diagnoses were read by five radiologists, in random order, from both the electronic display console and conventional multiformat images. All cases were reread after 1-month interval in a different random order viewing sequence and the opposite viewing modality
