  Purpose

This study will assess the repeatability of Magnetic Resonance Elastography (MRE) in both healthy volunteers and Hepatitis C Virus (HCV)-infected patients with fibrosis and lay the groundwork for the validation of MRE as an alternative to liver biopsy.


Condition Intervention Phase
Liver Fibrosis
Hepatitis C Virus
 Procedure: MRE
 Phase 1

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
Official Title: Test-Retest Repeatability Study of Magnetic Resonance Elastography (MRE) for Liver Fibrosis Assessment in Healthy Volunteers and Hepatitis C Virus-Infected Patients

Primary Outcome Measures:
  • Repeated Maximum Liver Elastic Stiffness (Kilopascal [kPa]) Measurements [ Time Frame: 14 days ] [ Designated as safety issue: No ]
    Reader evaluated 4 sections of the liver at 4 different time points and the end result was a single region of interest (ROI) that could be measured in the registered elastograms at each of the time points. Stiffness measures obtained using the "Individual ROI" (average of the 4 individual ROI's selected by the reader, one for each slice of liver) and "Common ROI" (intersection (or area of common overlap) of the 4 individual ROI's) analysis methods were compared. The mean was the overall mean of the data and the standard deviation was the within participant standard deviation.

  • Repeated Mean Liver Elastic Stiffness (kPa) Measurements [ Time Frame: 14 days ] [ Designated as safety issue: No ]
    Reader evaluated 4 sections of the liver at 4 different time points and the end result was a single ROI that could be measured in the registered elastograms at each of the time points. Stiffness measures obtained using the "Individual ROI" (average of the 4 individual ROI's selected by the reader, one for each slice of liver) and "Common ROI" (intersection (or area of common overlap) of the 4 individual ROI's) analysis methods were compared. The mean was the overall mean of the data and the standard deviation was the within participant standard deviation.

  • Percent Difference in Mean Liver Stiffness Between Hepatitis C Virus (HCV)- Positive Participants With Liver Fibrosis and Healthy Participants [ Time Frame: 14 days ] [ Designated as safety issue: No ]
    Reader evaluated 4 sections of the liver at 4 different time points and the end result was a single region of interest (ROI) that could be measured in the registered elastograms at each of the time points. Stiffness measures obtained using the "Individual ROI" (average of the 4 individual ROI's selected by the reader, one for each slice of liver) and "Common ROI" (intersection (or area of common overlap) of the 4 individual ROI's) analysis methods were compared.

  • Percent Difference in Maximum Liver Stiffness Between HCV- Positive Participants With Liver Fibrosis and Healthy Participants [ Time Frame: 14 days ] [ Designated as safety issue: No ]
    Reader evaluated 4 sections of the liver at 4 different time points and the end result was a single region of interest (ROI) that could be measured in the registered elastograms at each of the time points. Stiffness measures obtained using the "Individual ROI" (average of the 4 individual ROI's selected by the reader, one for each slice of liver) and "Common ROI" (intersection (or area of common overlap) of the 4 individual ROI's) analysis methods were compared.

Primary Completion Date: January 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: MRE Procedure: MRE

Part 1: Participants will have a screening visit, followed ~1 month later by two imaging visits over ~14 days. Each imaging visit will consist of two liver MRE scans.

Part 2: Participants will have a screening visit, followed ~1 month later by one imaging visit. The imaging visit will consist of two liver MRE scans.
