Are you interested in participating in clinical research about ultrasounds? Ultrasounds are one of the most common ways to take images of the inside of your body. In some cases, something called a contrast agent is injected through an IV to make your organs even more visible during the ultrasound. Researchers in this clinical trial are comparing a new type of contrast agent to the current type used in ultrasounds. Participants must be 19 years old and considered to be generally healthy. The study is taking place in Kansas City, Missouri, and Omaha, Nebraska.
