This clinical trial is focused on studying a new technique for imaging the lymphatic system, which is a part of the body’s immune system. The study involves using a method called contrast enhanced ultrasound to help visualize the lymphatic vessels. This technique is being tested to see if it can effectively show the superficial lymphatic vessels, which are the small channels that help transport lymph fluid throughout the body.

The treatment being used in this study is a special type of ultrasound contrast agent called Sonazoid, which contains the active substance perflubutane. This contrast agent is injected into the skin to help improve the visibility of the lymphatic vessels during the ultrasound imaging process. The study aims to determine how well this contrast agent works in making the lymphatic vessels more visible.

The purpose of the study is to evaluate the feasibility of using contrast enhanced ultrasound for lymphatic imaging. Participants in the study will receive an injection of the contrast agent, and then ultrasound imaging will be performed to see how well the lymphatic vessels can be visualized. The study is designed to gather information on the effectiveness of this imaging technique, which could potentially lead to better ways of diagnosing and understanding conditions related to the lymphatic system.
