Methods to Detect Liver Fibrosis

Overview

The goal of this study is to learn more about liver fibrosis and methods to detect it. We will evaluate and compare multiple MRI based measures of liver fibrosis in subjects with and without liver disease.

Detailed Description

While liver biopsy is still considered the gold standard for diagnosing and assessing the presence and degree of liver fibrosis and inflammation, it has disadvantages including the potential for sampling error and risk of complications, including life-threatening bleeding. New imaging modalities such as MR Elastography, T1 mapping, T2 mapping, T1 rho, and magnetization transfer allow rapid, non-invasive evaluation of liver parenchymal characteristics and may be able to detect and quantify parenchymal fibrosis alleviating the need for biopsy. To date, the quantitative performance of these different techniques has not been extensively studied. This study is a single-center trial of non-invasive MR imaging techniques aimed at detecting and measuring liver fibrosis. Once optimized, these technologies may later be deployed in hypothesis driven research studies and/or routine clinical exams in the pediatric population here at CCHMC and/or as part of a multi-center study with specific IRB approval for that project. To assess the relative performance of each technique, correlation across techniques, and reproducibility across the range of fibrosis, 32 subjects will be enrolled in this preliminary study sub-divided into 4 groups (Group 1: Healthy/ Normal controls; Group 2: F1/F2 fibrosis as determined by prior biopsy (low grade fibrosis group); Group 3: F3/F4 fibrosis as determined by prior biopsy (high grade fibrosis group), Group 4: Hepatic steatosis with fibrosis (NAFLD group)). 8 healthy subjects without known or suspected liver disease will be enrolled as normal controls. 8 subjects each with known fibrosis based on liver biopsy within the last 6 months will be enrolled in Group 2 and Group 3 (total = 16). 8 subjects with known hepatic steatosis and liver fibrosis based on liver biopsy within the last 6 months will be enrolled in Group 4.

Interventions

  • Device: MRI
    • MRI scan performed on 1.5T Philips Ingenia MRI scanner.

Arms, Groups and Cohorts

  • Active Comparator: Health/Normal Controls
    • Health/normal control subjects will undergo MRI using several different imaging sequences (MR Elastography, T1 mapping, T2 mapping, T1 rho, and magnetization transfer) designed to detect and quantify hepatic fibrosis.
  • Active Comparator: F1/F2 fibrosis
    • Type 1 and 2 liver fibrosis subjects will undergo MRI using several different imaging sequences (MR Elastography, T1 mapping, T2 mapping, T1 rho, and magnetization transfer) designed to detect and quantify hepatic fibrosis.
  • Active Comparator: F3/F4 fibrosis
    • Type 2 and 3 liver fibrosis subjects will undergo MRI using several different imaging sequences (MR Elastography, T1 mapping, T2 mapping, T1 rho, and magnetization transfer) designed to detect and quantify hepatic fibrosis.
  • Active Comparator: Hepatic steatosis with fibrosis
    • Hepatic steatosis with liver fibrosis subjects will undergo MRI using several different imaging sequences (MR Elastography, T1 mapping, T2 mapping, T1 rho, and magnetization transfer) designed to detect and quantify hepatic fibrosis.

Clinical Trial Outcome Measures

Primary Measures

  • MR imaging vs. histologic scoring in hepatic fibrosis
    • Time Frame: 2 years
    • Correlate the results from the different imaging sequences designed to detect and quantify hepatic fibrosis

Secondary Measures

  • MRI reproducibility
    • Time Frame: 2 years
    • evaluate the reproducibility of each of the tested MRI-based liver fibrosis quantification sequences

Participating in This Clinical Trial

Inclusion Criteria Group 1: 1. Healthy subjects with no known or suspected liver disease 2. Age 8 – 21 years Groups 2 and 3: 1. Biopsy confirmed liver fibrosis (F1/F2 Group 2, F3/F4 Group 3) 2. Age 8 – 21 years Group 4: 1. Biopsy confirmed hepatic steatosis AND biopsy confirmed liver fibrosis (any stage) 2. Age 8 – 21 years Exclusion Criteria All subjects: 1. Subjects <8 years of age and >21 years of age. 2. BMI > 35 kg/m2 3. Subjects deemed to possibly require sedation to undergo MR imaging 4. Inability to lie still for 90 minutes 5. Routine exclusions to MRI – e.g., implanted hardware 6.
