| 中文摘要: |
| 目的 探讨MRI对骨肉瘤的诊断价值。方法 对56例经临床手术后病理学证实的骨肉瘤MRI影像学资料进行回顾性分析评估。结果 MRI对骨肉瘤诊断准确率为100%,可清楚地显示髓腔内跳跃性病变。T2加权STIR像可精确地发现骨肉瘤对骨骺的侵犯 (准确率90.5%)。结论 MRI可精确地判断骨肉瘤对骨骺、关节、髓腔的侵犯,对评价化疗反应和制订手术方案有重要意义。 |

| Objective To investigate the MRI features of osteosarcoma. Methods MRI of 56 cases of osteosarcoma was retrospectively analyzed and was confirmed by pathology after operation. Results The diagnostic accuracy of osteosarcoma of MRI was 100%. It could show skip lesion in the medullary cavity. T2-weighted STIR image could accurately detected epiphyseal extension of osteosarcoma (90.5%). Conclusion MRI can accurately detect epiphyseal,joint, medullary cavity extension of osteosarcoma. |
