echogenicity

During ultrasound examinations, sometimes echogenicity is higher in certain parts of body.

This is because microbubbles have a high degree of echogenicity.

The liver is usually enlarged but maintained normal echogenicity.

Otherwise the appearing echogenicity may not be evaluated.

However, thrombi that have developed recently have low echogenicity and thus will not show up on ultrasound.

The ultrasound system converts the strong echogenicity into a contrast-enhanced image of the area of interest.

In other words, Echogenicity is higher when the surface bouncing the sound echo reflects increased sound waves.

The echogenicity difference between the gas in the microbubbles and the soft tissue surroundings of the body is immense.

Ultrasonography reveals a "bright" liver with increased echogenicity.

Usually the echogenicity compared to the deltoid muscle is homogeneous intensified without dorsal echo extinction.

Women with polycystic ovary syndrome may also show an increase in stromal echogenicity.

Microbubbles have a high degree of echogenicity, which is the ability of an object to reflect the ultrasound waves.

To accurately evaluate the echogenicity of an ultrasound, one has to take into account the physical laws of reflection, absorption and dispersion.

Ultrasound monitoring was not possible as impeller rotation generated multiple tiny bubbles that produced a diffuse intraluminal echogenicity.

Fatty liver could cause increased echogenicity in the liver, especially if the liver transaminases are elevated.

Ultrasounds of animals who have eaten the contaminated food in most cases show cortical echogenicity, perirenal fluid and pyelectasia.

Echogenicity (misspelled sometimes as echogenecity) is the ability to bounce an echo, e.g. return the signal in ultrasound examinations.

Microbubble gas core: The gas core is the most important part of the ultrasound contrast microbubble because it determines the echogenicity.

Heavy gases are less water-soluble so they are less likely to leak out from the microbubble to impair echogenicity (McCulloch et al., 2000).

Increase in echogenicity of echolucent carotid plaques after treatment with total triterpenic fraction of Centella asiatica: a prospective, placebo-controlled, randomized trial.

The microbubbles reflect a unique echo that stands in stark contrast to the surrounding tissue due to the orders of magnitude mismatch between microbubble and tissue echogenicity.

Ultrasound is routinely used in the evaluation of cirrhosis, where it may show a small and nodular liver in advanced cirrhosis along with increased echogenicity with irregular appearing areas.

Anisotropy is also a well-known property in medical ultrasound imaging describing a different resulting echogenicity of soft tissues, such as tendons, when the angle of the transducer is changed.

To avoid the different tendon echogenicities caused by different instrument settings, Middleton compared the tendon's echogenicity with that of the deltoid muscle, which is still lege artis.

Thus, ultrasonic imaging using microbubble contrast agents enhances the ultrasound backscatter, or reflection of the ultrasound waves, to produce a unique sonogram with increased contrast due to the high echogenicity difference.
