Abstract
Over the past 2 decades, groups of computer scientists, electronic design engineers, and physicians, in universities and industry, have worked to achieve an electronic environment for the practice of medicine and radiology. The radiology component of this revolution is often called PACS (picture archiving and communication systems). More recently it has become evident that the efficiencies and cost savings of PACS are realized when they are part of an enterprise-wide electronic medical record. The installation of PACS requires careful planning by all the various stakeholds over many months prior to installation. All of the users must be aware of the initial disruption that will occur as they become familiar with the systems. Modern fourth generation PACS is linked to radiology and hospital information systems. The PACS consist of electronic acquisition sites—a robust network intelligently managed by a server, multiple viewing sites, and an archive. The details of how these are linked and their workflow analysis determines the success of PACS. PACS evolves over time, components are frequently replaced, and so the users must expect continuous learning about new updates and improved functionality. The digital medical revolution is rapidly being adopted in many medical centers, improving patient care and the success of the institution.
