Evaluation of Liver Fibrosis Staging With Acoustic Radiation Force Impulse Elastography

February 1, 2012 updated by: Yonsei University

Prospective Cohort Study for Evaluation of Liver Fibrosis Staging With Acoustic Radiation Force Impulse Elastography in Patients With Chronic Liver Disease and Healthy Liver/Kidney Donors

This is a prospective cohort Study for evaluation of liver fibrosis staging with acoustic radiation force impulse elastography in patients with chronic liver disease and healthy liver/kidney donors.

Study Overview

Status

Completed

Detailed Description

A recent new method for liver fibrosis assessment based on similar technology to transient elastography is acoustic radiation force impulse (ARFI) imaging. ARFI has the advantages which can be conducted in parallel ways of measuring points in the patients with chronic liver disease when they underwent routine ultrasound examination. Thus, the aim of this study was to identify the normal range of ARFI velocity and assess the best cut-off value by recruiting healthy living liver and kidney donors.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
chronic liver disease
Any cause of liver disease that involves a process of progressive destruction and regeneration of the liver parenchyma leading to fibrosis and cirrhosis such as hepatitis B, hepatitis C, alcoholic liver disease.
Acoustic radiation force impulse (ARFI) imaging were measured 10 times in each patient.The region of interest was chosen in an area where the normal liver parenchyma was at least 6 cm thick and free of large blood vessels was chosen. A measurement depth of 2 cm below the liver capsule was chosen to standardize the examination.
Other Names:
  • ARFI imaging
Healthy liver and kidney donor
Healthy liver and kidney donor who have normal liver condition

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Evaluation of ARFI velocity in healthy donors and patients with chronic liver disease
Time Frame: 2 years
Measurement of ARFI velocity is non-invsive ultrasonographic technique. It is performed with a abdominal convex probe which is same probe as conventional ultrasonography. Short-duration acoustic radiation forces result in shear-wave propagation away from the region of excitation and are tracked using ultrasonic correlation-based methods. This results are called ARFI velocity which is expressed as meters per second
