Implementing a PACS within the radiology department is relatively straightforward; current vendor offerings work reasonably well with respect to image delivery to the traditional reading room. However, radiologists are not the only medical personnel who view (or create) images. Efficient mechanisms for the ubiquitous distribution of digital images throughout the health-care enterprise are essential to realize the most important benefits of the PACS. These benefits include the substantial cost savings when one no longer has to print and deliver film throughout the enterprise as well as the presumed improvement in patient care when health-care providers throughout the enterprise have immediate access to medical images.
