Ultrasound elastography
Updates to Article Attributes
Ultrasound elastography, also called as sono-elastography, is a modern evolutionary method of sonographic imaging. Techniques include shear wave elastography (also known as transient elastography) and strain elastography (also known as static or compression elastography). These techniques assess the mechanical properties of tissues such as stiffness and elasticity in response to a mechanical pressure on a tissue using sound waves. These techniques are used to detect different pathologies in tissues using the differences of their aforesaid mechanical properties.
Ultrasound elastography is increasingly used as a non invasive method to assess the degree of liver fibrosis in chronic liver disease and grade it accordinglybecause of the prognostic value1.
Physics
The tissue stiffness is calculated using the physical property of tissue called Young's modulus. The Young's modulus is defined as the association between the tissue strain(the force given for a unit surface area) and tissue stress (tissue deformation) in a material.
Applications
Sonographic Elastography has multiple clinical applications and used in 2,
- to assess degree of hepatic fibrosis and characterization of liver lesions.
- to assess diffuse renal parenchymal changes and characterization of renal lesions.
- breast mass diagnosis.
- prostate cancer detection
- thyroid lesion characterization
- tendon imaging
