A modernization framework for the leaders who own the vision, the risk and the budget.

Your legacy PACS may be the most expensive system you own, and the most exposed.

Healthcare digitized decades ago and then, in many ways, stood still. Walk through radiology today and digital acquisition is the norm, while much of the infrastructure underneath it is a decade or more past its design life and no longer receiving security patches. That is the contradiction a legacy PACS sits at the center of.

Most organizations frame modernization backwards, asking what it costs to upgrade instead of what it costs to keep the old system running. This paper reframes the question, sets out what to evaluate before you modernize, and shows why modernization runs over several contract cycles rather than a single project.

What you'll learn

  • Why the real cost question is not what modernization costs, but what it costs to keep legacy running
  • How an aging PACS becomes a route in for attackers, and why that risk can outweigh replacement cost
  • A six-factor framework for evaluating modernization through a business lens
  • The questions to ask about your own data before you migrate it
  • How a phased approach lets you modernize across the enterprise while keeping annual spend predictable
