Identify the magnetic resonance imaging (MRI) features that are mostimportant for preoperative characterization and local staging ofsoft-tissue sarcomas. Present a reporting checklist of the MRI features of soft-tissue sarcomas for assisting the surgical oncologist in the planning of patient management.
Sarcomas are the most common type of soft-tissue tumor.
Most of them occur in the extremities (43%),
but many of these tumors also display a predilection for the viscera,
trunk and the head and neck region. Table 1 summarizes the age distribution of soft-tissue sarcomas. MRis the imaging modality of choice for local staging,
monitoring response to therapy,
and surveillance for recurrence.
MRI features can be nonspecific and overlap with more common pathologic...

Knowledge of MRI features characteristic of soft-tissue sarcomas is esential to avoid the delay in diagnosis and to assist the surgical oncologist in the planning of patient management.
In some cases,
MRI allows to establish the preoperative diagnosis of the histological subtype sarcoma. The management of soft-tissue sarcomas is challenging,
and patients should be referred to tertiary centers experienced in the diagnosis and treatment of these tumors.
