Comparative and Additive Diagnostic Performance of Magnetic Resonance Elastography (MRE) and Corrected-T1 (cT1) for Fibrosis and Inflammation in Nonalcoholic Steatohepatitis (NASH) Using Histology As Reference

Comparative and Additive Diagnostic Performance of Magnetic Resonance Elastography (MRE) and Corrected-T1 (cT1) for Fibrosis and Inflammation in Nonalcoholic Steatohepatitis (NASH) Using Histology As Reference

This pilot study will evaluate conventional and investigational MR imaging and spectroscopic sequences and collect data to help plan more definitive future studies.

This prospective pilot study evaluates the comparative and additive diagnostic performance of Magnetic Resonance Elastography (MRE) and corrected-T1 (cT1) for the detection and staging of fibrosis and inflammation in Nonalcoholic Steatohepatitis (NASH), using histology as the reference standard.

• Subject has been fully informed and has personally signed and dated the written Informed Consent and Health Insurance Portability and Accountability Act (HIPAA) documents
• Subject has had or is expected to have a clinical or research biopsy within 150 days of the MR exam

Exclusion Criteria:

• VA subject
• < 18 years of age
