摘要
目的通过对骨肉瘤患者行MRI扫描,并与CT、X线平片相比较,总结骨肉瘤的MRI影像特点及评价MRI在骨肉瘤的诊断价值。方法本文收集17例骨肉瘤患者,均经MRI、CT及X线平片检查,并通过手术病理证实。结果骨肉瘤MRI上可表现瘤骨、骨质破坏骨膜反应、软组织肿块等征象。在骨髓浸润的显示、肿瘤与肌肉、血管、神经、相邻关节的关系、跳跃病灶的显示及骨肉瘤内出血和坏死的显示,MRI明显优于CT和X线平片,对骨肉瘤纵向浸润范围的显示,MRI明显优于X线平片,对其横向范围的显示,MRI与CT无明显差别。结论MRI能准确显示骨肉瘤的浸润范围及肿瘤内基本病变的情况,为临床制定手术方案提供了重要的影像学信息。
[Objective] To summarize the MRI signs of osteosarcoma and to evaluate MRI in diagnosing osteosarcoma through comparing the results of MRI with CT and X-ray. [Methods] 17 osteosarcoma patients proved by biopsy were examined by MRI, CT and X-ray. [Results] The signs of osteosarcoma in MRI were tumor bone, bone destruction, periosteal reaction, and soft tissue mass, MRI was superior to CT and X-ray in demonstrating intraosseous extension; skip focus; the relationship of bone tumor with vessel, nerve, muscle and adjacent joint; bleeding and necrosis in osteosarcoma. MRI was superior to X-ray in the demonstration of longitudinal extents of osteosarcoma too, but there was no significant difference in the demonstration of the cross extents in the same cross section of CT and MRI. [Conclusion] MRI can demonstrate the extension and basic pathological changes of osteosarcoma accurately, and provide much more important imaging information for surgical operation.
