Description
Sulfur hexafluoride is an ultrasound contrast agent indicated for use •in echocardiography to opacify the left ventricular chamber and to improve the delineation of the left ventricular endocardial border in adult patients with suboptimal echocardiograms •in ultrasonography of the liver for characterization of focal liver lesions in adult and pediatric patients
Indication
Echocardiography: Sulfur hexafluoride is indicated for use in adult patients with suboptimal echocardiograms to opacify the left ventricular chamber and to improve the delineation of the left ventricularendocardial border. Ultrasonography of the Liver: Sulfur hexafluoride is indicated for use with ultrasound of the liver in adult and pediatric patients to characterize focal liver lesions.
Mechanism of Action
Within the blood, the acoustic impedance of Lumason microspheres is lower than that of the surrounding non-aqueous tissue. Therefore, an ultrasound beam is reflected from the interface between the microspheres and the surrounding tissue. The reflected ultrasound signal provides a visual image that shows a contrast between the blood and the surrounding tissues.
Pharmacokinetics
- Absorption
- The pharmacokinetic of the SF6 gas component of Lumason was evaluated in 12 healthy adult subjects (7 men and 5 women). After intravenous bolus injections of 0.03 mL/kg and 0.3 mL/kg of Lumason, corresponding to approximately 1 and 10 times the recommended doses, concentrations of SF6 in blood peaked within 1 to 2 minutes for both doses.
- Distribution
- In a study of healthy subjects, the mean values for the apparent steady-state volume of distribution of SF6 were 341 L and 710 L for Lumason doses of 0.03 mL/kg and 0.3 mL/kg, respectively. Preferential distribution to the lung is likely responsible for these values.
- Metabolism
- SF6 undergoes little or no biotransformation; 88% of an administered dose is recovered unchanged in expired air.
- Elimination
