目的：探讨磁共振在骨良性肿瘤与肿瘤样病变诊断中的价值。材料和方法：搜集骨良性肿瘤与肿瘤样病变３４例，分析其磁共振表现。全部病例均做磁共振检查。采用常规ＳＥ序列，Ｔ１Ｗ及Ｔ２Ｗ成像。其中２０例同时做了脂肪抑制成像。结果：磁共振诊断正确率为９４．１％（３２／３４）。磁共振征象包括：骨质破坏（３０／３４）；软组织肿块（３／３４）；关节侵犯（１／３４）；骨壳（１０／３４）；硬化缘（１７／３４）；钙化（３／３４）；骨间隔（７／３４）；囊变坏死（８／３４）；出血（７／３４）；软组织水肿（３／３４）；髓腔水肿（３／３４）；关节积液（３／３４）。结论：磁共振是骨良性肿瘤与肿瘤样病变的有效辅助诊断方法。磁共振与平片、ＣＴ相结合有利于提高定性诊断正确率。
Objective: To investigate the value of magnetic resonance imaging in the diagnosis of benign bone tumors and tumor-like lesions. Materials and Methods: 34 cases of benign tumors and tumor-like lesions were collected and their magnetic resonance manifestations were analyzed. Magnetic resonance examinations were performed in all cases. Conventional SE sequences, T1W and T2W imaging were used. In 20 cases, fat suppression imaging was performed at the same time. Results: The diagnostic accuracy of magnetic resonance was 94.1% (32/34). Magnetic resonance signs include: bone destruction (30/34); soft tissue mass (3/34); joint invasion (1/34); bone shell (10/34); hardened margin (17/34); calcification (3/ 34); interosseous septum (7/34); cystic necrosis (8/34); hemorrhage (7/34); soft tissue edema (3/34); medullary edema (3/34); joint effusion (3/ 34). Conclusion: Magnetic resonance imaging is an effective auxiliary diagnosis method for benign bone tumors and tumor-like lesions. The combination of magnetic resonance, plain film and CT helps improve the accuracy of qualitative diagnosis.
