Precise differential and qualitative diagnoses for extremities soft tissue tumors(STTs) are of vital importance. Dynamic susceptibility contrast perfusion MRI(DSC-MRI) enables assessment of overall tumor vascularity, allowing indirect evaluation of the biological aggressiveness of tumors. Therefore, this study aims to discuss the feasibility of DSC-MRI to preliminarily assess in the differentiation between benign and malignant extremities STTs. Our results showed that DSC-MRI might be a non-invasive imaging technique that can play a role in identifying malignant and benign STTs in limbs and provide reliably pathological or physiological information for clinic.
