It depends on your existing bandwidth, the PACS system and your access scenarios.
You should have sufficient bandwidth in place to support the PACS system itself and possibly its connection to your EMR system.
Between the latter and the user - it truly depends. Even bandwidth hungry applications can be tamed by two solutions that can be deployed in combination:
1. WAN optimization technology. These performance enhancing proxies can help overcome the limitations of the TCP protocol, which is often not capable to use the existing bandwidth when faced with packet loss and latency. Secondarily, these systems can often serve up repeating content from the proxy sitting locally and closest to the users by securely caching the bitstream of the information (not the images or entire files).
2. Application and desktop virtualization can confine the bandwidth requirements of the EMR application to the datacenter, where bandwidth is cheaper than on the WAN. High performance protocols cans effectively deliver a remote representation of the application and the the user interaction with the application with significantly less badnwidth the client application itself.
