| 中文摘要: |
| 目的 确定软骨母细胞型骨肉瘤的MRI增强形式与组织病理学的相关性。方法 对14例软骨母细胞型骨肉瘤患者术后标本的组织病理学表现与增强MRI的增强形式进行对比研究。结果 软骨母细胞型骨肉瘤的间隔强化和边缘强化区代表肿瘤的纯软骨成分,无强化区和不均匀强化区代表肿瘤的软骨和骨样成分。结论 增强MRI可以通过确定成骨区和软骨区来辅助获得诊断软骨母细胞型骨肉瘤的活检材料。 |

| Objective To identify the MRI enhancement patterns of chondroblastic osteosarcoma correlated with histopathology. Methods The histopathological findings of the surgical specimens of 14 patients with chondroblastic osteosarcoma were compared with enhancement patterns on enhanced MR images. Results In chondroblastic osteosarcoma septal and peripheral rim enhancement represented tumour with a pure chondroid matrix. Non-enhancing and heterogeneous enhancing areas represented tumour with both chondroid and osteoid matrix. Conclusion Enhanced MR imaging can assist in obtaining diagnostic biopsy material of chondroblastic osteosarcoma by identifying both osteoid- and chondroid-forming areas. |
