Another name for Lumason is sulfur hexafluoride lipid-type A microspheres.
Understanding Lumason: An Ultrasound Contrast Agent
Lumason is a specialized ultrasound contrast agent used in medical imaging to enhance the visibility of certain structures or blood flow during an ultrasound examination. It is administered as an injectable suspension, designed for either intravenous or intravesical use, depending on the diagnostic need.
The Chemical Identity of Lumason
The active substance in Lumason is sulfur hexafluoride lipid-type A microspheres. This name specifically refers to the microscopic bubbles filled with sulfur hexafluoride gas, which are encapsulated by a lipid (fat-like) shell. These microspheres are crucial for its function as a contrast agent, as they reflect sound waves more efficiently than surrounding tissues, thereby improving the clarity of ultrasound images.
Here's a quick overview of its identification:

How Lumason Works in Medical Imaging
When injected into the body, the sulfur hexafluoride lipid-type A microspheres travel through the bloodstream. During an ultrasound scan, these microspheres resonate and reflect the ultrasound waves, creating a stronger signal that helps differentiate blood flow or delineate specific organs or lesions more clearly than a standard ultrasound. This enhanced visualization can be vital for diagnosing various conditions, particularly those affecting the heart, liver, or urinary tract.
Important Safety Considerations
As with any medical substance, it's essential to be aware of safety considerations. Lumason is contraindicated in patients who have a known or suspected hypersensitivity to sulfur hexafluoride lipid microsphere or any of its components. This includes substances like polyethylene glycol (PEG), which is part of the formulation. Patients should always inform their healthcare provider about any allergies or sensitivities before receiving Lumason.
