Medical ultrasound

ultrasoundultrasonographymedical ultrasonography
Contrast-enhanced ultrasound (CEUS) is the application of ultrasound contrast medium to traditional medical sonography. Thus, ultrasonic imaging using microbubble contrast agents enhances the ultrasound backscatter, (reflection) of the ultrasound waves, to produce a sonogram with increased contrast due to the high echogenicity difference.
A contrast medium for medical ultrasonography is a formulation of encapsulated gaseous microbubbles to increase echogenicity of blood, discovered by Dr Raymond Gramiak in 1968 and named contrast-enhanced ultrasound.

Microbubbles

microbubblemicro- bubbles
Commercially available contrast media are gas-filled microbubbles that are administered intravenously to the systemic circulation. Targeting ligands that bind to receptors characteristic of intravascular diseases can be conjugated to microbubbles, enabling the microbubble complex to accumulate selectively in areas of interest, such as diseased or abnormal tissues.

Tissue (biology)

There is a great difference in echogenicity between the gas in the microbubbles and the soft tissue surroundings of the body.

Contrast-enhanced ultrasound can be used to image blood perfusion in organs, measure blood flow rate in the heart and other organs, and for other applications. (Normally, they would exit the heart through the pulmonary artery and be stopped by the lungs.) This form of bubble contrast medium is generated on an ad hoc basis by the testing clinician by agitating normal saline (e.g., by rapidly and repeatedly transferring the saline between two connected syringes) immediately prior to injection.
