1. Resection of liver-limited metastases from colorectal cancer is the current standard of care 2. Selection criteria for hepatic resection of colorectal metastases include: attainability of complete removal of gross disease; adequate liver functional reserve following surgery (minimum of 25% of healthy liver in normal patients); and at least two contiguous hepatic sectors with sufficient vascular inflow and outflow 3. More than 3 masses, masses 5 cm or greater, and bilobar disease are negative prognostic factors but not exclusion criteria for resection 4. MRI is superior for the detection and characterization of liver metastases from colorectal cancer

1. Rationale for surgical treatment of colorectal hepatic metastases 2. Criteria used to select patients that will benefit from resection A. Historic criteria B. Current criteria 3. Spectrum of imaging appearances of colorectal hepatic metastases 4. Review sensitivities of various modalities (CT, MRI, PET) 5. Critical radiologic features which impact the surgeon’s decision A. Number and location of the metastatic lesions B. Total volume of metastatic lesions and volume of expected normal remaining hepatic parenchyma following resection C. Proximity to portal vein, hepatic artery, biliary tree
