Imaging BiomarkerDevelopment of an Imaging Biomarker for Hepatic Fibrosis Using Gadoxetate Disodium

Inclusion criteria:

• subjects with Hepatitis C who are scheduled to obtain a liver biopsy in the future or have obtained a liver biopsy in the 6 months prior to planned MR imaging or
• subjects who are healthy, without liver disease (used for normal controls)

All subpopulations regarding gender, race and ethnicity will have equal opportunity for inclusion in the study protocol. The study protocol only includes adult population consistent with the age (>21 years old) at presentation.

Exclusion criteria:

• subjects with any contraindication to obtaining an MRI with intravenous contrast including: metal in body, severe renal impairment, pregnancy, or breast feeding. Contraindications will be identified using the same screening questionnaire as is provided for routine clinical examinations.
• Subjects with history of allergy to MRI contrast dye

Severe renal impairment is defined as a glomerular filtration rate (GFR) < 30 mL/min/1.73 m2. All subjects will be screened with a questionnaire. The GFR will be calculated in any subject who reports kidney problems or a history of kidney problems using blood chemistries performed within 6 weeks of the planned date of the MRI examination. These blood chemistries would need to have been performed as part of routine clinical care. A potential subject who reports kidney problems or a history of kidney problems who does not have blood chemistries available within 6 weeks of the MRI examination will be excluded from participation in this study.
