Preoperative MR images of 174 patients with soft-tissue sarcoma were analyzed by two readers. Imaging findings concerning T-staging, osseous, articular and neurovascular invasion were correlated with intraoperative findings/histopathology. To assess neurovascular invasion contact between tumor and vessels/nerves was classified. MR imaging allows reliable and accurate local staging of soft-tissue sarcoma. Neurovascular invasion should be diagnosed, if the contact between tumor and vascular/neural circumference exceeds 180°.
