To prospectively compare efficiency and outcome of a standard film-only system with those of a digital picture archiving and communication system (PACS).
The film-only system, which used either analog film or computed radiography (CR) hard copy, was compared with a PACS, which used CR images displayed on a multiviewer in the radiology department and a workstation in the medical intensive care unit. A random sample of nonroutine, bedside chest radiographs was studied.
Within 20 minutes of completion of radiography, 246 of 328 (75%) of the images were available at the workstations; it took 1.8 hours for 238 of 317 (75%) of the images to be displayed on the multiviewer. When the workstation was used, the staff did not access the image information earlier, but clinical actions were initiated more promptly in response to imaging findings. Consultation with radiologists decreased from 507 of 561 (90%) images with hard copies to 70 of 249 (28%) with the workstation.
Use of a PACS improves the delivery of chest images, facilitates the initiation of clinical actions, and decreases input by radiologists.
前瞻性比较标准的仅使用胶片的系统与数字图像存档与通信系统（PACS）的效率和结果。
将使用模拟胶片或计算机X线摄影（CR）硬拷贝的仅使用胶片的系统与一个PACS进行比较，该PACS使用在放射科的多画面显示器和医学重症监护病房的工作站上显示的CR图像。对非例行的床边胸部X线照片进行随机抽样研究。
在完成X线摄影后的20分钟内，328张图像中有246张（75%）在工作站可用；317张图像中有238张（75%）在多画面显示器上显示需要1.8小时。使用工作站时，工作人员没有更早获取图像信息，但针对影像学发现更迅速地启动了临床行动。与放射科医生的会诊从561张硬拷贝图像中的507次（90%）降至249张工作站图像中的70次（28%）。
使用PACS可改善胸部图像的传递，促进临床行动的启动，并减少放射科医生的工作量。
