Medical imaging data is growing fast across the NHS.
From CT and MRI scans to X-rays, ultrasounds, and AI-assisted diagnostics, imaging studies are growing in both volume and complexity. And as the studies become more complex, so does the challenges around them: each one needs to be stored securely, accessed quickly, retained appropriately, and protected over the long term.
But while imaging activity is typically planned and measured by study, traditional storage models are often based on capacity. That creates a difficult mismatch.
As imaging demands rise, NHS trusts face increasing pressure from capacity costs. Finance and procurement teams must plan for demand that is hard to predict. IT teams need to over-provision storage to avoid shortfalls. And clinical teams still need fast, reliable access to patient imaging data whenever it is required.
For NHS trusts, the question is no longer just how much storage they need, but how confidently they can plan for the demand ahead.
Why Traditional Storage Models Are Under Pressure
Medical imaging data is growing in two ways: study volumes are rising, and individual study sizes are increasing.
That makes capacity forecasting harder. NHS trusts may be able to predict imaging activity, but study size can vary significantly by modality, clinical complexity, imaging protocol, and future demand.
When storage is priced by capacity, that variability creates cost uncertainty.
There is operational risk too. Picture Archiving and Communication Systems (PACS) and imaging contracts can run over long periods, while the underlying storage infrastructure may need refreshing sooner. That can introduce mid-contract migration, added cost, and disruption for already stretched IT teams.
Moving From Capacity-Based Costs to Per-Study Pricing
Through Everpure, Evergreen//One™ for Medical Imaging introduces a different approach.
Instead of charging based on storage volume, it allows NHS trusts to move to a predictable per-study model. This aligns storage costs more closely to the way imaging services are planned and delivered.
A contract-guaranteed price per study gives NHS trusts greater visibility over long-term costs, even as individual imaging study sizes change. It also provides a simpler basis for planning, using the study as the measure rather than projected storage capacity. This helps reduce the pressure created by capacity-based procurement. NHS trusts can move away from buying storage ahead of demand, reducing waste and limiting exposure to rising storage volumes.
As an SLA-led model, Evergreen//One™ for Medical Imaging supports performance, resilience, and continuity, helping keep critical studies available when clinicians need them.
By reducing exposure to refresh cycles and migration risk, the model can also help NHS trusts avoid some of the disruption associated with traditional storage infrastructure.
From IT Cost Centre to Strategic Enabler
Imaging storage is often discussed in technical terms, but the choices NHS trusts make around it can shape cost control, clinical access, resilience, and long-term planning. A per-study model helps make those choices clearer. By linking storage cost more closely to imaging activity, it gives teams a simpler way to plan, compare long-term value, and understand what they are paying for.
That clarity matters because imaging storage directly affects how quickly clinicians can access studies, how reliably services can run, and how confidently NHS trusts can prepare for new ways of working.
When storage is built around predictable pricing, defined service levels, and long-term continuity, it becomes easier for NHS trusts to plan for the future of medical imaging with confidence.
Making the Move to Per-Study Storage
NHS trusts need an imaging storage strategy that can support clinical priorities, reduce financial uncertainty, protect performance, and limit operational risk.
CDW can help NHS partners explore what Everpure’s per-study model could mean in practice. With technical expertise, healthcare understanding, and procurement experience, CDW supports teams as they assess current storage challenges, understand the financial impact of capacity-led models, and evaluate the value of moving to per-study predictability.
That includes helping teams consider not only cost and capacity, but the performance clinicians depend on to access critical studies quickly and reliably.
It also means helping bring the right stakeholders into the conversation, from finance and procurement to IT and clinical teams, so decisions are made collectively around shared priorities.
