Welcome to the SonoWorld Contrast-Enhanced Ultrasound Minisite
Here you will find a wide range of resources to help you learn about Contrast-Enhanced Ultrasound (CEUS), microbubbles, blood flow assessment, clinical utility of CEUS and many other topics related to the rapidly expanding field of Contrast-Enhanced Ultrasound.
What IS Contrast-Enhanced Ultrasound (CEUS)
Current CEUS agents are based on gas-filled microbubbles that are strongly reflective of ultrasound. When a bolus of microbubble contrast agent is injected intravenously it circulates through the body and greatly enhances acoustic backscatter from the blood wherever the agent is present. Contrast-Enhanced Ulrtrasound (CEUS) enhances the ability of conventional ultrasound imaging to detect and assess blood flow within the vascular system, organs and lesions.
Because Contrast-Enhanced Ultrasound does not involve use of ionizing radiation, there is increasing interest for its use in the pediatric population and for monitoring disease states over time where frequent re-examination is required.
Although Contrast-Enhanced Ultrasound is approved in the United States for only heart chamber opacification and for focal liver lesion characterization, it is used for an ever-increasing range of applications in other countries. In Europe it has become most widely used for evaluating liver lesions and in evaluations of the vascular system. Research continues on use of CEUS for assessment of organ perfusion.
There is also great interest in the use of ultrasound contrast agents as carriers of therapeutic agents such as genetic materials or chemotherapeutic materials. Conventional ultrasound imaging systems can be modified to image contrast agents at low power, and to destroy the bubbles by using higher power ultrasound to induce bubble collapse, releasing the attached therapeutic material precisely where needed.
Here in the SonoWorld Contrast-Enhanced Ultrasound minisite we will assemble educational resources to help you learn about Contrast-Enhanced Ultrasound, and explore the clinical applications that have been developed world-wide for this new diagnostic tool. You will find lectures on contrast enhanced ultrasound, cases that utilize CEUS to reach or enhance the diagnosis, Articles on Contrast-Enhanced Ultrasound, and News Stories related to ultrasound contrast agents.
Contrast-Enhanced Ultrasound (CEUS) also sometimes referred to as "Ultrasound Contrast" is the use of a natural or manufactured material that produces strong reflections of ultrasound waves, that can be injected into the body, enhancing the reflectance of ultrasound during ultrasound imaging.
