Liver elastography produces ultrasound waves that generally do not strike the liver causing a stress reaction. Liver elastography is a non-invasive, painless, objective ultrasound test that generally does not affect the patient’s liver. By generating low frequency ultrasound waves, liver elastography measures the elasticity and hardness of diseased tissues on the basis of two-dimensional ultrasound images with the help of the ARFI imaging principle; it can be used for the diagnosis of benign liver diseases, such as cirrhosis and hepatic fibrosis, and can also be used for the preliminary differential diagnosis of benign and malignant tumors of the liver. For patients with suspected chronic liver disease, liver elastography is often required on top of routine ultrasound; patients need not worry about the impact of ultrasound generated by elastography on the liver. Patients with abnormal liver elastography results are advised to seek prompt medical attention to identify the cause of the abnormality.
