Follow-up of musculoskeletal tumours. 2. Metastatic disease

Both the prognosis and the morbidity of a patient with a primary malignant musculoskeletal tumour have improved over the past 25 years due to the advent of adjuvant chemotherapy and limb-sparing surgery. This has important implications for the role of imaging at the time of initial diagnosis and during follow-up.

The optimal imaging strategy will be stressed.
