kontrastiultraheliga

Kontrastiultraheliga, also known as contrast-enhanced ultrasound (CEUS), is a medical imaging technique that uses ultrasound contrast agents to enhance the visualization of blood flow and tissue perfusion. These contrast agents are typically microbubbles of gas encapsulated in a lipid shell, which are injected intravenously. When the ultrasound waves interact with these microbubbles, they reflect the sound waves differently than surrounding tissues, creating a brighter signal on the ultrasound image. This allows for improved detection and characterization of abnormalities, such as tumors or vascular lesions, by highlighting their vascular patterns. CEUS is a real-time imaging modality, meaning that the contrast enhancement can be observed as it occurs, providing dynamic information about the vasculature. It is considered a safe procedure as the contrast agents are generally well-tolerated and excreted from the body quickly. CEUS has found applications in various medical specialties, including radiology, cardiology, and gastroenterology, for the evaluation of organs like the liver, kidneys, heart, and spleen. Its ability to visualize microvasculature and distinguish between different tissue types based on their vascularity makes it a valuable diagnostic tool.
