Sulfur hexafluoride (Lumason) is a medical contrast agent used for ultrasound imaging. It is a clear, colorless, and odorless liquid that is injected into the bloodstream, where it forms tiny bubbles that reflect ultrasound waves. This allows for enhanced visualization of blood vessels, organs, and other structures within the body.
Lumason is primarily used for ultrasound-guided procedures such as biopsies, drainages, and vascular access. It is also used to visualize the bladder, ureters, and renal pelvis during urologic procedures. Additionally, it is used to visualize the biliary system during ERCP procedures.
One of the main advantages of Lumason over other contrast agents is its high echogenicity, which means it reflects more ultrasound waves than other agents. This results in better image quality and greater visibility of the structures being imaged. Additionally, it has a long half-life permitting multiple imaging sequences to be performed during a single examination.
Lumason is generally well-tolerated, with few reported adverse effects. The most common side effects include mild discomfort or pain at the injection site, and a warm or flushed sensation. These side effects are usually short-lived and do not require treatment.
