摘要
目的:探讨MRI在骨髓炎诊断中的价值。方法:回顾分析20例骨髓炎的X线、MRI平扫及Gd-DTPA增强扫描资料。结果:MRI最早可在发病第3天发现骨髓信号异常,骨髓炎在MRI上表现出T1WI为低或稍低信号,在T2WI上呈高信号,以STIR或FFE序列最明显,Gd-DTPA扫描病变不均匀强化,骨髓炎多有脓肿和脓肿壁环状强化。结论:MRI对骨髓炎的诊断具有重要价值,尤其在显示早期病变及病变范围方面明显优于X线。
Objective: To evaluate the value of MRI in diagnosis of the osteomyelitis. Methods: 20 patients with osteomyelitis which has been proved by diagnosis of operation, biopsy of pathology or clinic have been examined by X-ray, plain MRI and Gd-DTPA enhanced MRI. Results: The MRI can discover the marrow abnormal signal as early as on the third day when the disease emerges. The osteomyelitis displays low or slightly low signal on the T1WI, high signal on the T2WI, and more higher on the STIR or FFE, but shows uneven enhancement on Gd-DTPA-enhanced scans, the osteomyelitis always has the abscess, and the wall of the abscess always has circular enhancement. Conclusion: The MRI is of great value in the diagnosis of osteomyelitis, especially the MRI is superior to the X-ray in themanifestation of earlier period disease and disease scope.
