mikrobuborékkontrasztanyagokat

Mikrobuborékkontrasztanyagok, often referred to as microbubble contrast agents, are diagnostic tools used in medical imaging, particularly in ultrasound. These agents are tiny gas-filled spheres, typically ranging from 1 to 10 micrometers in diameter. Their primary function is to enhance the visualization of blood flow and tissue structures during ultrasound examinations. When injected intravenously, these microbubbles circulate with the blood. Their physical properties, such as their shell composition and the gas encapsulated within, are carefully designed to be safe and biocompatible.

The acoustic properties of microbubbles differ significantly from those of blood and surrounding tissues. When hit by ultrasound waves, the microbubbles resonate and scatter the sound energy in a way that is much stronger than the surrounding biological tissues. This difference in acoustic backscatter allows ultrasound machines to detect and amplify the signal originating from the microbubbles. By analyzing the distribution and movement of these microbubbles, clinicians can gain detailed insights into blood perfusion within organs, identify blockages or abnormalities in blood vessels, and assess the viability of tissues. Their application is expanding in areas such as cardiology, oncology, and radiology for improved diagnostic accuracy and characterization of various medical conditions.
