The objectives for this study include: * Testing a unique way of imaging people with colorectal cancer and other cancers that has spread to the liver using magnetic resonance imaging (MRI); * Seeing if the MRI process can be used across multiple imaging platforms; * Determining whether the results of the imaging can be reproduced; * Reviewing how MRI results relate to cancer response to combination therapy and to clinical endpoints.
