Radiomics as a value layer in RIS/PACS: from image to structured data

For years, RIS and PACS systems have served as the operational core of digital radiology: they store, distribute and display images. But the growth of artificial intelligence and precision medicine is pushing these systems to evolve.

In this new landscape, radiomics should not be understood as a standalone algorithm, but as a value layer that turns the medical image into structured, traceable, reusable data. For a RIS/PACS developer like NOVA Imaging, the key question is: how should the system be prepared to enable, scale and govern radiomics?

From pixel to data: a paradigm shift for the RIS/PACS

Traditionally, the medical image has been a visual object. Radiomics breaks that paradigm by turning it into a source of quantitative data: texture, shape, intensity or heterogeneity features that describe tissue objectively.

That introduces a deep change in the role of the RIS/PACS:

It no longer just manages studies
It begins to produce, store and orchestrate derived data
It becomes an advanced clinical information platform

In that context, the system’s value lies not only in displaying images, but in structuring the knowledge that emerges from them.

Radiomics as a functional layer of the system

For radiomics to be viable at clinical scale, it has to be integrated as a cross-cutting layer of the RIS/PACS, not as an experimental module.

That means the system must be able to:

Associate radiomic features with studies, series and regions of interest
Maintain full traceability (source image, algorithm version, parameters)
Manage results as structured data, not as isolated files
Integrate with AI engines, analytics and advanced reporting

A RIS/PACS prepared for radiomics understands that this data is part of the diagnostic cycle, just like the report or the original study.

Structured reporting and digital biomarkers

One of the biggest impacts of radiomics shows up in the radiology report. When the extracted features are managed properly from the RIS/PACS, they can feed:

Structured reports
Quantitative indicators comparable over time
Reproducible digital biomarkers
Longitudinal patient follow-up

This opens the door to reports that are more objective, more measurable and aligned with data-driven medicine, without the radiologist losing clinical control.

Interoperability and data reuse

From a developer’s perspective, radiomics forces you to think about interoperability from the design stage.

A modern RIS/PACS has to let radiomic data:

Be shared through APIs or standards
Be reusable by multiple applications
Feed external predictive models
Integrate with research or clinical analytics platforms

Here, the system’s architecture matters as much as the algorithm. Without a solid foundation, radiomics stays confined to pilots with no real impact.

Scalability, governance and trust

Clinical adoption of radiomics depends not only on its technical potential, but on trust in the system that supports it.

For that reason, a RIS/PACS has to account for:

Versioning of data and algorithms
Auditability and reproducibility
Quality control and validation
Clinical data governance

When those capabilities are built into the core of the system, radiomics stops being a future promise and becomes a real operational capability.

Conclusion

Radiomics is not the future of radiology on its own. The real change happens when the RIS/PACS evolves from an image manager into a structured data platform.

In that scenario, systems like the ones built by NOVA Imaging play a key role: they do not just host images, they enable new ways of generating clinical value from them.
