Elastography
Updates to Article Attributes
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
Sono-elastography
Sono-elastography is the term used when ultrasound is used to assess elastography
strain elastography (also known as static or compression elastography)
shear wave elastography (also known as transient elastography)
MR elastography
MR elastography is is the term used when MRI is used to assess tissue stiffness. It uses shear waves to assess the tissue displacement in all directions making it more precise than sonoelastography.
MR elastography has been most widely used in cases of liver fibrosis where larger lesions can be easily assessed even in the presence of ascites.
Uses
differentiating malignant and benign neoplasms (especially breast)
identifying early traumatic changes in muscles and tendons
aiding in deciding the biopsy site more accurately, reducing negative biopsy rates
assessing liver fibrosis 3
assessing liver steatosis (eg non-alcoholic fatty liver disease and steatohepatitis)
assessing cervical insufficiency , reducing rates of preterm birth or miscarriage 4
