Contrast-enhanced ultrasound is a medical imaging technique that improves the visualization of blood flow and tissue perfusion by using microbubble contrast agents. These contrast agents, which are typically gas-filled bubbles, enhance the echogenicity of blood, making it easier to identify and differentiate between various tissues and abnormalities during an ultrasound exam. This technique is particularly useful for assessing vascular structures and evaluating conditions such as tumors and liver diseases.
congrats on reading the definition of contrast-enhanced ultrasound. now let's actually learn it.
