Abstract

Digital Variance Angiography (shortly DVA) is a novel imaging technology used in the field of interventional radiology. Its use is primarily studied in lower-limb vascular diagnostics and interventions and based on the promising results of in-silico and retrospective clinical studies, a prospective clinical trial has been performed showing the remarkable dose-lowering capability of this technology, which is an all-time important goal in medicine regarding radiation safety. DVA can also be combined with a relatively un-investigated technology called color-coded angiography, which is based on visualizing flow related functional data to increase the efficiency and safety of vascular interventions. The use of this technique has been investigated during prostatic artery embolization with promising results and a retrospective analysis of lower-limb color-coded angiographies was also performed to compare color-coded DVA with color-coded digital subtraction angiography. The results of the latter investigation showed that color-coded DVA can reproduce the same data as a previously marketed method.
