On June 9, 2026, ICUS submitted written comments to the FDA urging the agency to repurpose approved ultrasound contrast agents for broader use throughout the body.
Utrasound contrast agents (sometimes also known as ultrasound enhancing agents) are among the safest contrast media available in medical imaging, and their clinical benefits are well established across a wide variety of clinical settings.
Moreover, a single intravenous injection of a UCA will show perfusion of all organs in the body and the choice of organ does not alter patient risk. By simply moving an external ultrasound transducer, a clinician can evaluate pathology across organ systems, following disease wherever it may be found.
