In an effort to help improve quality and encourage the appropriate use of ultrasound contrast, ASE established the ContrastZone website to provide the cardiovascular ultrasound community with a central place on the web to find both basic and advanced information about Ultrasound Enhancing Agents (UEA), also known as ultrasound contrast. This site includes links to recent ASE guidelines and standards, how-to videos, reimbursement information, and success stories from busy labs on how to incorporate UEAs into everyday practice to improve overall quality.

ASE Headquarters – COVID-19 Update

Beginning March 26, 2020, the county where the ASE Headquarters is located is under a government order to “Stay at Home” due to the spread of the coronavirus.
