低场磁共振成像在以腰背痛为首发症状的布氏杆菌脊柱炎中的诊断价值

目的：探讨布氏杆菌脊柱炎的影像特点及鉴别诊断。方法对12例布氏杆菌脊柱炎患者的磁共振成像（MRI）图像进行回顾性分析。结果布氏杆菌脊柱炎的患者可有不同程度的椎体受累，且均可见不同程度的软组织肿胀，但未见明显脓肿形成；6例增强扫描可见病变椎体内骨髓水肿部分均匀强化，椎旁软组织肿胀影均匀强化，其内未见无强化的脓腔。结论低场MRI对以腰背痛为首发症状的布氏杆菌脊柱炎具有重要的诊断价值，增强扫描对布氏杆菌脊柱炎的诊断有特殊的诊断意义。

Low-field MRI diagnostic value for brucellosis spondylitis with back pain as the first symptoms

Objective To explore the imaging features and differential diagnosis of brucellosis spondylitis. Methods Retrospective analysis of 12 patients with brinell coli spondylitis′ MRI images. Results Brucella Spondylitis patients had a different degree of vertebral body involved, and could have different degree of soft tissue swelling, but no obvious abscess formation;By enhanced scan of 6 cases, part of marrow edema had homogeneous en-hancement, which can be seen within the vertebral bone, paraspinal soft tissue swelling shadow with homogeneous enhancement, within which no enhancement of the abscess. Conclusion Low-field MRI has important diagnostic val-ue on brucellosis spondylitis with back pain as the first symptoms, and enhanced scan have special diagnostic signifi-cance for the diagnosis of brucellosis spondylitis.
