摘要
目的:探讨骨巨细胞瘤的MRI表现及其诊断价值。方法:回顾性分析经手术病理证实的16例骨巨细胞瘤患者的临床及MRI表现。结果:肿瘤在T1WI上以中等信号为主,夹杂低信号或高信号,T2WI上以中等信号为主,夹杂小片状高信号。MRI对软组织蔓延等侵袭性特征的显示明显优于普通X线片及CT。结论:MRI能改善对软组织蔓延等侵袭性特征的评价,可提高对骨巨细胞瘤诊断的准确性,并指导制定治疗方案。
Objective：To study the MRI findings and their value in the diagnosis of giant cell tumor of bone.Methods：The clinical materials and MRI findings of 16 cases with surgery and pathology proven giant cell tumor of bone （GCT） were retrospectively analyzed. Results：The tumors presented as predominantly intermediate signal intensity accompanied with hypo-and/or hyperintensity foci on T1WI,and predominantly intermediate signal intensity with patchy hyperintensities on T2WI.Soft tissue invasion by tumor assessed on MRI was superior to that of CT and radiography.Conclusion：The assessment of invasiveness of GCT manifesting as soft tissue mass could be evaluated on MRI,which is helpful to improve the accuracy of diagnosis and the guidance of treatment planning.
