The mini-PACS (Picture Archive and Communication System) as you are aware is a type of PACS that is specific to one type of medical imaging modality, such as computed tomography (CT) or magnetic resonance imaging (MRI). The current trend today is toward full PACS RIS integration however. This presents many advantages, as this will facilitate sharing of these images over different platforms, improving diagnoses and allowing for greater opportunities for consultations when needed.

This process is already going on at large for-profit medical centers and major university hospitals; however, for smaller health care facilities and non-profits, often the decision is more complex. This is particularly true of specialty clinics and radiology facilities that focus on one type of medical issue and a single type of modality. Is it better to go with a mini-PACS that serves present needs and deal with the problem of integration when it comes, or should the facility make the costly investment of a full PACS-RIS?

Fortunately, drops in the cost of technology have made such components as the PACS server more affordable for smaller and less well-funded clinics and health care facilities. The web-based PACS makes integration of older specialized systems much less expensive than even a few years ago; prices on a fully-functional PACS-RIS that is capable of reading, processing and storing a wide range of medical images in various modalities start at around $5000.

Granted, a lower-end PACS-RIS will have some limitations; however, it may be the best choice for smaller clinics as it will allow the facility continue to provide much-needed patient services while upgrading its equipment in stages as finances allow.

Keep in mind that due to several factors, there is currently a shortage of qualified radiologists. With a web-based PACS possible to consult with a radiologist almost anywhere in the country. It is possible to add a radiology component to an existing mini-PACS for a reasonable cost; in fact, many such specialized systems have elements  radiology imaging built-in.

If yours in a clinic that deals with a single modality, just be aware that because of economics, demographics and a greater need for efficiency, the trend is toward full PACS integration; stand-alone applications will become increasingly rare. Advance planning and some research into the various PACS options available will be of great help for smaller clinics, non-profit facilities and even private practices when it comes to preparation for full PACS integration and the moving toward the establishment of a full-service facility.
