Freon 218
Freon 218 Uses, Dosage, Side Effects, Food Interaction and all others data.
Freon 218, a diagnostic drug that is intended to be used for contrast enhancement during the indicated echocardiographic procedures, is comprised of lipid-coated microspheres filled with octafluoropropane(OFP) gas. When exposed to ultrasound waves, the microspheres resonate and "echo" strong signals back to the ultrasound machine. The difference in density between the gas-filled bubbles and the blood around them creates an increased level of contrast visible in the resulting ultrasound image. During echocardiography, activated Freon 218 enhances images of the inner edges or borders of the heart, producing an improved image that may enable physicians to better diagnose patients.
Freon 218, a diagnostic drug that is intended to be used for contrast enhancement during the indicated echocardiographic procedures, comprised of lipid-coated microspheres filled with octafluoropropane(OFP) gas. It provide contrast enhancement of the endocardial borders during echocardiography. The perflutren lipid microspheres exhibit lower acoustic impedance than blood and enhance the intrinsic backscatter of blood.

Uses
Freon 218 is a diagnostic medication to improve contrast during echocardiograms.
Used as an ultrasound contrast imaging in cardiology and radiology.
How Freon 218 works
Freon 218 is comprised of gas-filled microspheres that are injected or infused into the body. When exposed to ultrasound waves, the microspheres resonate and "echo" strong signals back to the ultrasound machine. The difference in density between the gas-filled bubbles and the blood around them creates an increased level of contrast visible in the resulting ultrasound image. During echocardiography, activated Freon 218 enhances images of the inner edges or borders of the heart, producing an improved image that may enable physicians to better diagnose patients.
Toxicity
There is new temporal evidence that perflutren may be associated with new-onset seizure activity following perflutren microbubble contrast injection during dobutamine-atropine stress echocardiography. [PMID: 23432576]
