One of the motives for putting in a picture archiving and communication sys
tem (PACS) is to improve efficiency and hence enhance the competitive stren
gth of the radiology department. Many would argue that it is now negligent
to consider installing an old fashioned conventional radiology department r
ather than a PACS. In considering the issue it is important to be clear abo
ut the nature of the competition facing radiologists. This varies depending
on the country and upon whether the institution is public or private. PACS
can potentially help to overcome this competition in two ways: by providin
g real-time radiology, and by enabling teleradiology. Success in these area
s requires state-of-the-art implementations of PACS, particularly clinicall
y relevant PACS software, and adequate staffing levels. (C) 1999 Elsevier S
