The increase in treatment possibilities and the survival improvement in metastatic disseminated diseases urges radiologists to a more accurate description in number, location and vascular relations of liver metastasis. Familiarization with postreatment changes relating to local therapy (surgery, radiofrequency, stereotactic body radiation therapy or transarterial chemoembolization) and after systemic treatment, (with typical conventional cytotoxic agents or molecular targeted therapy) is mandatory for the oncological radiologist. Due to the increasing use of new molecular targeted therapy, features such as attenuation and contrast intake have to be taken into account when evaluating postreatment response, besides morphologic parameters.

-Spectrum of findings in pretreatment metastatic lesions, focusing on MRI characteristics. -MRI as the most accurate imaging modality in the detection and characterization of small lesions: DWI and biliary elimination contrasts. -Postreatment changes in liver parenchyma: steatosis, pseudocirrhosis, nodular regenerative hyperplasia. -Postreatment changes in metastatic lesions: Conventional chemotherapy, cytotoxic effects, RECIST evaluation. Molecular targeted chemotherapy changes in attenuation and vascularity: CHOI, Bevacizumab, immunomodulatory therapy.
