CO₂

Increased diagnostic insight

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).
