Optison is used in contrast-enhanced ultrasound to enhance the image and reduce misdiagnosis and missed diagnosis. Currently, contrast agents are approved only for cardiac imaging, though new studies demonstrate the benefits of use in other applications such as detecting cancers, monitoring chronic gastrointestinal diseases, identifying vascular disease and diagnosing heart disease.
The ICUS, a medical society that represents cardiologists, radiologists and other physicians and imaging professionals, commends the label change that would remove the boxed warnings from both ultrasound contrast agents currently approved in the U.S.
