Benefits of elastography include:
- Diagnostically accurate
- Noninvasive; safer than a biopsy
- More cost-effective than many other tests such as CT and MRI
- Can be performed as part of a routine ultrasound study
Ultrasound elastography is FDA-approved for the non-invasive measurement of liver stiffness to evaluate patients with suspected liver disease for fibrosis. Elastography is particularly useful for screening at-risk patients for severe liver fibrosis and cirrhosis, such as patients with hepatitis B and C, and those with hepatic steatosis and non-alcoholic steatohepatitis (NASH). Some medications may also cause liver fibrosis. Faculty at UT Southwestern are also investigating the use of elastography in the differentiation of benign and malignant tumors in the thyroid, lymph nodes, liver, and elsewhere.
