Coping with PACS downtime in digital radiology.

As radiology departments become increasingly reliant on picture archiving and communication systems, they become more vulnerable to computer downtime that can paralyze a smoothly running department. The experiences and strategies developed during various types of picture archiving and communication system (PACS) downtime in a large radiology department that has completely converted to soft copy interpretation in all modalities except mammography are presented. Because these failures can be minimized but not eliminated, careful planning is necessary to minimize their impact.
