(CEUS) Contrast agents increase the reflection of ultrasonic energy, improve the signal to noise ratio and caused by that the detection of abnormal microvascular and macrovascular disorders. Contrast enhanced ultrasound is used in abdominal ultrasound (liver sonography) as well as in cerebrovascular examinations e.g., for an accurate grading of carotid stenosis. The used contrast agents are safe and well tolerated.

The quality of the enhancement depends on:
point the concentration of the contrast agent;
point the type of injection, flow rate;
point the patient characteristics;
point the microbubble quality and properties of the filling gas and the shell.
The additional use of ultrasound contrast agents (USCAs) may overcome typical limitations like poor contrast of B-mode imaging or limited sensitivity of Doppler techniques. The development of new ultrasound applications (e.g., blood flow imaging, perfusion quantification) depends also from the development of pulse sequences for bubble specific imaging. In addition, contrast enhanced ultrasound improves the monitoring of ultrasound guided interventions like RF thermal ablation.

Intro, 
Historical Development,

etc.MRI Resource Directory:<br> - Contrast Agents -
 
Albunex and Infoson, used mainly in cardiac evaluations, are first generation one-pass-only contrast agents and have been replaced by the new-generation contrast media. Albunex and Infoson are the same sonicated human serum albumin microbubbles. Infoson is licensed and manufactured in Europe, while Albunex was produced in the USA.
Albunex, an air-filled microbubble with a denatured albumin shell (modified from air-filled albumin microspheres prepared from sonicated 5% human serum albumin), was the first FDA-approved contrast agent, but is no longer in production.
Cardiac shunts and valve regurgitations are often evaluated with Color Doppler Imaging (CDI), which also improved with injections of Albunex, but this agent is pressure-sensitive and does not recirculate. It is effectively a one-pass-only agent, limiting its clinical efficacy.

Bubble DestructionMRI Resource Directory:<br> - Contrast Agents -
 
Bubble destruction describes the microbubble shell rupture by ultrasound pulses. The bubble destruction increases with increasing peak negative pressure and decreasing frequency. The mechanical index is an indicator for the effectiveness of microbubble destruction. Contrast enhanced ultrasound relies on bubble rupture to detect bubbles in small vessels.

ClutterMRI Resource Directory:<br> - Artifacts -
 
Clutters are unwanted components of the received signal. In contrast enhanced ultrasound, clutter often describes the part of the received echo that is not from microbubble contrast agents.

FocusMRI Resource Directory:<br> - UltraSound Physics -
 
In contrast enhanced ultrasound, the focus is the point at which maximum bubble destruction occur.
The transmit focus is the region on the axis of an ultrasound beam where the width of the beam has a minimum value. All waves crossing the focus are in phase in relation to the transducer surface or to the electronic summing point of an electronically focused array.
