An Investigational Scan (Intravoxel Incoherent Motion Diffusion Weighted Imaging) for the Evaluation of Colorectal Cancer Liver Metastases Treatment Response

This trial evaluates the treatment response of colorectal cancer that has spread to the liver (liver metastases) using intravoxel incoherent motion diffusion weighted imaging (IVIM DWI). IVIM DWI is new kind of imaging scan that may help measure changes in disease before and after chemotherapy in patients with colorectal liver metastases.
