Picture Archive Communication Systems (PACS)

Paper Summary:

This paper explains that digital radiology applications of picture archiving communications systems (PACS) provide improved workflow and faster turnaround times by virtue of instant display of images thereby facilitating immediate diagnosis. The author points out that radiology information systems and picture archive communication systems provide a radical departure from the traditional current film and chemical imaging applications by meeting significant and unfulfilled needs for instant imaging and quick diagnosis both in the field and in the clinic. The paper relates that while these technologies were relatively expensive just a few years ago, their cost has dropped to the point where virtually all clinicians who feel their patients can benefit from them can afford to integrate them into their diagnostic regimen.

From the Paper:

"The authors report that observations of the radiologists in the clinical environment showed that they relied predominantly on interpretation of images from PACS to render their conclusions, with only occasional RIS terminal use and even less frequent HIS access. The principal explanation for this behavior most likely relates to the inconvenience of accessing such data: Three different computers are required to access three separate clinical systems (ie, PACS, RIS, HIS). The Internet was not used by attending radiologists to search for external medical evidence; instead, they relied on their training and experience to reach conclusions; however, residents frequently used the Internet and reference textbooks as a source of external information while they waited for the attending radiologist's review."
