Liver elastography involves the use of a surface ultrasound probe that delivers a low-frequency pulse or shear wave to a small volume of liver tissue under the rib cage. The transmission of the sound wave is completely painless. Patients are asked to lie flat on an examination table. A Radiologist places the probe between the ribs on the right side of the lower chest wall. A series of painless pulses are then applied to the liver. The results are recorded on the equipment and an overall liver stiffness score is generated. This score is then interpreted by a qualified radiologist to predict the likelihood of advanced fibrosis or cirrhosis.  Staging of fibrosis and fat quantification by UGAP technique is done.

Patients should be fasting  for a minimum of 3 hours before the test to increase the likelihood of obtaining reliable test results. The scan will take 10 to 15 minutes to complete.
