There are no specific MRI features which are diagnostic in bone and soft tissue sarcomas, but a combination of certain findings allows an accurate diagnosis in some cases including giant cell tumour, chondrosarcoma, liposarcoma, neurofibrosarcoma, aggressive fibromatosis and pigmented villonodular synovitis. MRI is the method of choice for staging bone and soft tissue sarcomas. It is of particular use for identifying satellite nodules and skip lesions within the same bone or anatomical compartment. CT scan is important for screening for pulmonary metastases, and bone scan remains useful for screening for distant skeletal disease. The biopsy should be planned and performed after any MRI examination. MRI is the most sensitive post-therapy evaluation for local recurrence of bone and soft tissue sarcoma.
在骨与软组织肉瘤中，没有特定的MRI特征可用于诊断，但某些发现的组合在某些情况下可实现准确诊断，包括骨巨细胞瘤、软骨肉瘤、脂肪肉瘤、神经纤维肉瘤、侵袭性纤维瘤病和色素沉着绒毛结节性滑膜炎。MRI是骨与软组织肉瘤分期的首选方法。它对于识别同一骨或解剖区域内的卫星结节和跳跃性病变特别有用。CT扫描对于筛查肺转移很重要，骨扫描对于筛查远处骨骼疾病仍然有用。活检应在任何MRI检查之后进行规划和实施。MRI是骨与软组织肉瘤局部复发的最敏感的治疗后评估方法。
