Tiny gas bubbles injected into a vein during an ultrasound scan, used to show blood flow in the heart and, in the liver, to tell different kinds of lump apart without radiation.
The WHO groups ultrasound contrast media under ATC V08DA: perflutren in human albumin (Optison), perflutren in phospholipid (Definity, Luminity in Europe), sulfur hexafluoride in phospholipid (Lumason, SonoVue in Europe) and perflubutane. Lumason's American label includes characterising focal liver lesions, and SonoVue's European indication includes liver and breast lesions on Doppler sonography. Perflutren products carry an American boxed warning on serious cardiopulmonary reactions. The elastography and contrast-enhanced ultrasound record covers the imaging technique.
Gas microbubbles a few micrometres across stay in the blood vessels and resonate in the ultrasound field, producing strong echoes that show perfusion in real time; contrast-specific imaging modes suppress the tissue signal.
Gas bubbles injected into a vein during a heart ultrasound to show the heart's pumping chamber more clearly when the ordinary picture is not good enough.
Gas bubbles in a protein shell injected into a vein during a heart ultrasound to show the heart's pumping chamber more clearly.
Tiny gas bubbles injected into a vein during an ultrasound scan. In the liver they show how a lump fills with blood, which helps tell liver cancer and other lesions apart without radiation.
