Carbon dioxide is used as a contrast agent for diagnostic
angiography and vascular interventions in both the
arterial and venous circulation. When injected into
a blood vessel, CO2 bubbles displace blood, allowing
vascular imaging. Because of the low density of the gas,
a digital subtraction angiographic technique is necessary
for optimal imaging. CO2
is twenty times more soluble
than oxygen and dissolves within 2–3 minutes after the
injection. It has been reported in several studies that
CO2
angiography does not affect the renal function....Consult any medical college hospital they will guide you further.
