microbubbles
Minuscule gas pockets
Microbubbles are tiny gas-filled spheres, typically less than a millimeter in diameter, used in medical imaging and therapeutic applications.
Injected into the bloodstream, they enhance ultrasound images by reflecting sound waves more effectively than surrounding tissue: The cardiologist used microbubbles to get a clearer view of blood flow through the heart.
In emerging treatments, microbubbles can deliver drugs to targeted sites when burst by focused ultrasound.
