It is injected into the vascular system and does not filter through the kidneys or cause a contrast reaction that may be seen with CT or MRI contrast agents. The introduction of these micro-bubbles has allowed the visualization of the tiny vessels in the parenchyma of the liver that was previously only studied with B mode and Doppler techniques with limited success.
