The correct spelling of the word "CEUS" is /siəs/, with the stress on the first syllable. It is derived from the Latin term "caelum," meaning "sky" or "heaven." In phonetic transcription, the "c" is pronounced as "s," the "e" as "i," and the "u" as "yoo." This term is commonly used in medical imaging to refer to Contrast-Enhanced Ultrasound, a diagnostic technique that uses ultrasound technology and contrast agents to visualize the blood flow in organs and tissues.
CEUS is an acronym that stands for Contrast-Enhanced Ultrasound. It refers to a medical imaging technique that utilizes ultrasound technology to create enhanced and detailed images of organs and tissues in the body.
Ultrasound, or sonography, is a non-invasive diagnostic tool that uses high-frequency sound waves to produce images of structures inside the body. CEUS takes this imaging modality a step further by introducing a special contrast agent into the bloodstream. These contrast agents are typically microbubbles filled with gas or a liquid that can enhance the visibility and improve the quality of ultrasound images.
During a CEUS examination, the contrast agent is injected into the patient's vein, and the ultrasound probe records the echoes produced as the microbubbles flow through the blood vessels. By analyzing the contrast-enhanced images, physicians can visualize blood perfusion, identify tumors, lesions, or abnormalities, and assess the viability or functionality of targeted organs.
CEUS is particularly useful in assessing liver lesions, characterizing kidney tumors, evaluating focal liver diseases, and monitoring tumor response to treatment. It is a safe and widely accessible imaging technique that does not involve ionizing radiation, making it advantageous for certain patient populations, such as pregnant women and children. It is often used in conjunction with other diagnostic tools, such as computed tomography (CT) or magnetic resonance imaging (MRI), to provide a comprehensive evaluation of various medical conditions.
