Our completed clinical study shows that Digital Variance Angiography (DVA) allows a very substantial reduction of DSA related radiation exposure in lower limb interventions, therefore this technology increases the safety of the endovascular procedures. It provides very significant radiation protection not only for the patients but also for the medical staff. The clinical results were published in Scientific Reports.
Our completed clinical study demonstrates that the quality reserve provided by our technology can be effectively converted to significant contrast media (50%) reduction in carotid angiography. This brings significant economical and health benefits - less adverse events, contrast induced nephropathy - to the patients and cost saving for the cath labs. The clinical study was published in the European Journal of Radiology Open.
Digital Variance Angiography (DVA) visualizes the same structures as DSA but offers dramatically better image quality (Gyano et al, 2019; Bastian et al, 2021; Thomas et al, 2021) and DVA significantly improves the image quality of angiograms even in CO2 angiography (Orias et al, 2019). This has a special significance since the use of CO2 as a contrast agent is the only possibility to treat patients with severe kidney injury. In CO2 angiography the image quality is improved also at a lower frame rate (1–3 fps), which provides an opportunity for substantial radiation exposure reduction (Gyano et al, 2020).

Our cooperation with Prof. Mahnken and his team started in 2019. The fruitful collaboration has already resulted in two peer-reviewed publications about the advantages of DVA. The clinical studies demonstrated the usability of DVA in lower-limb angiography in patients with metal implants and DVA’s better image quality in selective lower limb interventions.
