A new technique called Ultrasound-based Acoustic Radiation Force Impulse (ARFI)imaging is performed using standard approved ultrasound machines and transducers but the sound waves or impulses are produced in a different pattern. We are going to evaluate the usefulness of this new technique in diagnosing different liver conditions.

Condition Intervention
Liver Fibrosis
Liver Inflammation
Device: Ultrasound-Based Acoustic Radiation Force Impulse (ARFI)

Study Type: Interventional
Study Design: Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic

Primary Outcome Measures:
  • Acoustic Radiation Force Impulse Imaging [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
    To confirm that the sound waves and or impulses produced by this new ultrasound-based imaging effectively aids in the diagnosis of different liver conditions such as fibrosis and inflammation and/or rejection.

Enrollment: 62
Study Start Date: November 2012
Study Completion Date: May 2015
Primary Completion Date: May 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Ultrasound-based Acoustic Radiation Force Impulse (ARFI)
Research scans using the ultrasound-based acoustic radiation force impulse imaging technique will be completed. This research imaging will take approximately 5 to 10 minutes to complete.
Device: Ultrasound-Based Acoustic Radiation Force Impulse (ARFI)
Research scan using an ultrasound-based acoustic radiation force impulse will be used to image the liver. This is non-invasive and will take approximately 5 to 10 minutes to complete.
