This trial studies how well an investigational scan (magnetic resonance elastography [MRE]) works with standard imaging (magnetic resonance imaging [MRI]) in detecting response to treatment in patients with liver cancer that has spread to other places in the body. Diagnostic procedures, such as MRE with MRI, may make it easier for researchers to see if the treatment for liver cancer is working.
I. To evaluate the ability of magnetic resonance (MR) elastography (MRE) to detect changes in hepatocellular carcinoma (HCC) between baseline and after initial 6 weeks of treatment (change in MRE liver tumor stiffness compared to percent non-viable/necrotic tumor).
I. Correlate MRE imaging measurements with patient survival (overall survival and time to tumor progression) over 18 months.
II. Correlate MRE measurements with change in tumor size and enhancement on standard of care MR imaging sequences.
Patients undergo standard of care MRI and MRE over 60-90 minutes within 5 days of liver biopsy before receiving any medical treatment for HCC, at 6 weeks after medical treatment for HCC, and then every 12 weeks until disease progression.

The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; fluorescence imaging; and MICROSCOPY.
Spectroscopic method of measuring the magnetic moment of elementary particles such as atomic nuclei, protons or electrons. It is employed in clinical applications such as NMR Tomography (MAGNETIC RESONANCE IMAGING).
A technique applicable to the wide variety of substances which exhibit paramagnetism because of the magnetic moments of unpaired electrons. The spectra are useful for detection and identification, for determination of electron structure, for study of interactions between molecules, and for measurement of nuclear spins and moments. (From McGraw-Hill Encyclopedia of Science and Technology, 7th edition) Electron nuclear double resonance (ENDOR) spectroscopy is a variant of the technique which can give enhanced resolution. Electron spin resonance analysis can now be used in vivo, including imaging applications such as MAGNETIC RESONANCE IMAGING.
A type of MAGNETIC RESONANCE IMAGING that uses only one nuclear spin excitation per image and therefore can obtain images in a fraction of a second rather than the minutes required in traditional MRI techniques. It is used in a variety of medical and scientific applications.
The creation of a visual display of the inside of the entire body of a human or animal for the purposes of diagnostic evaluation. This is most commonly achieved by using MAGNETIC RESONANCE IMAGING; or POSITRON EMISSION TOMOGRAPHY.
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
