Evaluation of PACS in a medical intensive care unit: the effect of computed radiography

Preliminary data is presented from a prospective study of a Picture Archiving and Communication System (PACS) in a Medical Intensive Care Unit (MICU). These data compare the efficiency of image information communication and utilization when the MICU operates in a conventional manner using standard x-ray film as an image acquisition, storage and display medium and a digital manner when images are acquired by Computed Radiography (CR), transmitted and displayed digitally. The CR images were made available for viewing more quickly than conventional film images due to the increased automation provided by the management system of the PACS. Despite the improvement of the availability of images, the time required for the MICU physicians to utilize the image information did not change.
