Modern therapies have radically changed the approach to the patient with metastases, creating new challenges for the radiologist. Beyond the early diagnosis of cancer, there is a new attention toward early diagnosis of recurrence. Accurate assessment of disease extent and its morphostructural features (calcification, cavitation, hemorrhage, infection) have become crucial in the evaluation of the response to treatment. Cross-sectional imaging is exquisitely suited for this task. The publication provides the practicing radiologist with a systematic and analytical tool to address the polymorphous aspects of metastases on CT, with a prarticular emphasis on their modalities of diffusion, structure and more or less usual localizations
