Elastography Ultrasound
Elastography is a type of imaging test that checks your organs to see if they are stiffer than normal. Stiff areas in your organs may be a sign of disease. Elastography is mainly used to check the liver for stiffness. Stiff areas in the liver are a sign of scar tissue (fibrosis) caused by liver disease
What is the difference between ultrasound and elastography ?
Elastography directs painless low frequency vibrations into the liver. Ultrasound (US) or magnetic resonance imaging (MRI) measures how quickly these vibrations move through the organ. A computer uses this information to create a visual map showing the stiffness (or elasticity) of the liver.
What is ultrasound of the liver with elastography ?
Liver elastography involves the use of a surface ultrasound probe that delivers a low frequency pulse or shear wave to a small volume of liver tissue under the rib cage. The transmission of the sound wave is completely painless.
