Assessment of Portal Hypertension With Multiparametric MRI

ID#: NCT03436550

Age: 18 years - 66+

Gender: All

Healthy Subjects: Accepts Healthy Volunteers

Recruitment Status: Enrolling by invitation

Start Date: December 12, 2017

End Date: November 30, 2021

Summary: The purpose of this study is to determine whether new multiparametric magnetic resonance imaging (MRI) methods (including diffusion-weighted MRI, dynamic contrast-enhanced MRI, MR elastography and phase-contrast imaging) can be useful in assessing liver damage and degree of portal hypertension (a complication of advanced liver fibrosis and cirrhosis) secondary to chronic liver disease, compared to ultrasound measurement of liver stiffness [acoustic radiation force impulse (ARFI) ultrasound] and routine blood tests. MRI uses magnetic fields to look at soft tissues in the body. This study will ultimately help to determine whether these methods will be useful in identifying liver disease and their complications that cannot be well-understood using current liver MRI techniques.
Eligibility:

Inclusion Criteria:

- Chronic liver disease (including all etiologies of liver disease)

- 18 years of age and older

- Patient is able to give informed consent for this study

- Patients preferably (but not necessarily) underwent/will undergo:

2. Liver transplant or liver resection performed as part of routine clinical care and/or

3. Medical therapy for portal hypertension or TIPS placement as part of routine clinical care. Control group

- Healthy volunteers without history of liver disease (will be used for the purpose of image optimization). These subjects will NOT undergo HVPG measurement.
