Quantitative Validation of MRI Angiography via PACS Integration

The introduction of new imaging techniques such as advanced MRI angiography requires robust, quantitative validation methods. MTA Portal Central facilitates this validation through standardized data exchange between PACS systems and research databases.

Interoperability Pillars for Validation

Our platform is built on three core pillars:

• DICOM-QR & FHIR integrations: Automatic extraction of image parameters and (anonymized) patient context from clinical PACS.
• Reference Standards: A central library with validated measurement protocols for vascular image analysis.
• Exchange Formats: Standardized JSON schemas for sharing quantitative results between academic centers.

A recent implementation at two Dutch university medical centers showed that the time to validate a new MRI angiography technique could be reduced from 9 to 4 months. The interoperability layer enabled a seamless flow of DICOM images and associated clinical metadata to the MTA analysis environment.

Data Architecture and Security

All data is processed according to the 'privacy-by-design' principle. Images are anonymized in real-time upon extraction, and only the parameters necessary for technical validation are forwarded. The underlying infrastructure utilizes containerization, making analyses reproducible and auditable.

The future lies in further automating this pipeline, with the goal of providing real-time feedback to radiologists on the technical quality of acquired images. This directly contributes to clinical effectiveness and safety.
