| 中文摘要: |
| 目的 探讨MRI对四肢软组织良、恶性肿瘤及肿瘤样病变的鉴别诊断价值。方法 回顾分析26例经临床抗炎或手术病理证实为四肢软组织良、恶性肿瘤及肿瘤样病变的MRI表现,重点分析了MRI信号特点和肿瘤的增强情况。结果 MRI能准确地显示四肢软组织病变的大小、形态、信号强度以及侵犯范围;增强扫描有助于鉴别诊断。结论 MRI 对四肢软组织占位病变的诊断和鉴别诊断有着重要的意义。 |

| Objective To investigate the role of MR imaging in differential diagnosis of malignant tumors from benign tumors or tumor-like lesions in extremities. Methods MRI of 26 cases with histopathologically proved masses, including 8 maligant tumors, 8 benign tumors and 10 tumor-like lesions in the extremities were studied retrospectively. Features of signal intensity and contrast enhancement in MR images were analyzed with emphasis on lesion location. Results MRI may demonstrate accurately the size, sharpness, signal intensity, extension and site of lesions. Contrast-enhanced MR images may be useful for differential diagnosis of extremity lesions. Conclusion MRI is a very useful method in diagnosis and differential diagnosis of soft tissue lesions in extremities. |
