Abstract

Abstract: The Food and Drug Administration alert enhances our understanding of the mechanism of severe reactions to ultrasound-enhancing agents (UEAs). The known incidence of these reactions remains low and unchanged (1 in 10 000 administrations). Because the risk-to-benefit ratio for ultrasound contrast agents (UCAs) remains extremely low, we do not advise any changes to laboratory policy regarding indications for their use. The use of these agents should continue in situations where they have been shown to be impactful. Lipid-based UCAs (SonoVue and Luminity) are contraindicated in patients who have a history of prior hypersensitivity to these UEAs, to polyethylene glycol (PEG) (macrogol), or to PEG-containing products, such as certain bowel preps for colonoscopy or laxatives.
