| Abstract: | Objective To analse MRI appearances and diagnostic value of giant cell tumor of bone.Methods MRI features of giant cell tumor of bone proved by pathology in 14 cases were reviewed.Results The lesions located at distal femur in 7 cases,at approximal tibia in 3 cases,at distal humerus,approximal femur,thoracic vertebrae and sacrum in 1 case respectively.The characteristic appearances of MRI were cystic and solid masses,there was fluid-fluid level within tumors in company with bleeding.Tumors were slight low or low signal intensity on T1WI,slight high signal intensity on T2WI.Conclusion MRI is of significant value in diagnosis of bone giant cell tumor. |
