We are pleased to announce the publication of our latest prospective randomized controlled trial in European Radiology, demonstrating the clinical potential of Digital Variance Angiography (DVA) for dose-optimized interventional imaging.

In this study, we evaluated DVA in the context of prostatic artery embolization (PAE) – one of the most technically demanding interventional radiology procedures and a known source of high radiation exposure for both patients and operators.

Key Findings

• Up to 80% reduction in stationary acquisition–related radiation dose

• Significantly improved image quality compared with digital subtraction angiography (DSA)

• Superior visualization of small vessels and tissue blush, even under ultra-low-dose conditions

By leveraging the intrinsic image quality reserve of DVA, substantial dose reductions were achieved without compromising diagnostic confidence, supporting safer and more efficient workflow in complex interventions.

Why This Matters

Radiation protection remains a central pillar of modern interventional radiology. Our results highlight DVA as a powerful, vendor-independent image processing approach that aligns with the ALARA principle and has the potential to improve safety across a wide range of angiographic procedures.

This work reflects the mission of the Division of Experimental Imaging to translate advanced imaging technologies into clinically meaningful benefits – bridging innovation, patient safety, and interventional performance.
