Sulfur hexafluoride is a medication used in ultrasound to enhance viewing of blood vessels and the urinary tract. 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...
- Mechanism
- Curator reviewed
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.
