Magnetic Resonance Elastography for Assessment of Liver Fibrosis (MK-0000-132)(COMPLETED)
- Conditions
- Liver FibrosisHepatitis C Virus
- Interventions
- Procedure: MRE
- Registration Number
- NCT00896233
- Lead Sponsor
- Merck Sharp & Dohme LLC
- Brief Summary
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.

- Primary Outcome Measures
Name Time Method Repeated Mean Liver Elastic Stiffness (kPa) Measurements 14 days 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.
Repeated Maximum Liver Elastic Stiffness (Kilopascal [kPa]) Measurements 14 days 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.
Percent Difference in Mean Liver Stiffness Between Hepatitis C Virus (HCV)- Positive Participants With Liver Fibrosis and Healthy Participants 14 days 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.
