Elastography is a noninvasive test used to check the stiffness of the organs. It’s mostly used to look at the liver for signs of fibrosis. Your provider may order elastography if you’ve had inflammation or damage to the liver or have symptoms of cirrhosis. The test is usually quick and painless.
An elastography test is an imaging test that's mostly used to check for scarring in your liver (liver fibrosis). The scarring is caused by liver disease. Learn more.
Elastography is a non-invasive medical imaging technique that helps determine the stiffness of organs and other structures in your body. It is most commonly used to assess your liver. Elastography directs painless low frequency vibrations into the liver.
Liver elastography is an imaging procedure used to detect scar tissue and signs of liver damage. Learn more about liver elastography and what the procedure entails.
Magnetic resonance elastography (MRE) is a test that combines magnetic resonance imaging (MRI) with low-frequency vibrations to create a visual map called an elastogram. This test shows changes in body tissues caused by disease.
Elastography is any of a class of medical imaging modalities that map the elastic properties and stiffness of soft tissue. [ 1 ][ 2 ] The main idea is that whether the tissue is hard or soft will give diagnostic information about the presence or status of disease.
Ultrasound elastography (USE) is an imaging technology sensitive to tissue stiffness that was first described in the 1990s 1. It has been further developed and refined in recent years to enable quantitative assessments of tissue stiffness.
Elastography is a newer technique that exploits the fact that a pathological process alters the elastic properties of the involved tissue. This change in elasticity is detected and imaged using elastography. Radiographic technique. Sonoelastography is the term used when ultrasound is used to assess elastography.
Elastography is the set of techniques by which tissue stiffness is estimated as a physical property termed the Young’s modulus (E). The Young’s modulus is a proportionality constant that relates applied force per unit area or stress, and the resultant relative change in tissue dimension, or strain.
The general principle of elastography can be summarized as follows: (1) perturb the tissue using a quasi-static, harmonic, or transient mechanical source; (2) measure the resulting mechanical response (displacement, strain or amplitude and phase of vibration); and (3) infer the biomechanical properties of the underlying tissue by applying either...
