24hr Imaging Of HCC After EOVIST

Before the research starts (screening): After signing the consent form, the participant will be asked to undergo some screening tests or procedures to find out if they can be in the research study. Many of these tests and procedures are likely to be part of regular cancer care and may be done even if it turns out that the participant does not take part in the research study. If the participants has had some of these tests or procedures recently, they may or may not have to be repeated. * A medical history, which includes questions about the participant's health, current medications, and any allergies. * An assessment of your tumor by X-ray, CT (Computerized Tomography) scan, MRI (Magnetic Resonance Imaging) or PET (Positron Emission Tomography) scans. If these tests show that the participant is eligible to participate in the research study, the participant will begin the study. If the participant does not meet the eligibility criteria, they will not be able to participate in this research study. After the screening procedures confirm that the the participant is eligible to participate in the research study: In this research study, the investigators are looking to see if MR imaging with Eovist performed 24 hours after the injection of Eovist helps improve the identification and characterization of focal liver tumors. Currently, standard Eovist-enhanced MRI examinations include imaging up to 20 minutes after the injection of Eovist. The participant will undergo a routine, standard of care Eovist MRI examination of the liver. The participant will then be asked to return on the following day so that a repeat MRI examination may be performed at approximately 24 hours after your dose of Eovist. No additional injections will be performed on the 2nd day of imaging. Planned Follow-up: The investigators will follow the participant through the completion of their 24 hour MRI examination.
