| 摘 要： | 目的：探讨MRI对不典型脊椎结核的诊断价值。方法：回顾性分析21例经手术病理证实的脊椎结核患者的影像资料。结果：21例脊椎结核患者，术前行X线检查21例，CT检查19例，MRI检查21例；14例X线平片及10例CT检查阴性；7例X片示单椎体破坏区位于椎体后缘，呈溶骨性破坏、压缩骨折；9例CT显示相邻椎体病变，椎间盘变窄、椎体无明显破坏；无多个椎体跳跃破坏，椎小关节受累、椎旁软组织肿块内未见明确脓肿形成；MRI检查21例中，20例显示病变椎体呈长T1长T2信号，抑脂序列呈不均匀高信号，16例显示椎间隙变窄，间盘裂隙状强化，17例显示椎旁脓肿，以上20例确诊为椎体结核。1例MRI显示椎旁软组织肿块内无脓肿形成，疑诊为肿瘤。结论：MRI对不典型脊椎结核诊断敏感度、特异度及准确性均高于其他影像检查，能为临床提供更有价值的信息。

| Abstract: | Objective:To study the value of MRI in the diagnosis of atypical spinal tuberculosis.Methods:The imaging materials of 21 cases with surgery and pathology proven tuberculosis of spine were collected and retrospectively analyzed.Results:Of the 21 cases,imaging examinations included radiography(21 cases),CT(19 cases) and MRI(21 cases).14 cases with X-ray plain film and 10 cases with CT shown negative results before surgery.7 cases showed osteolytic destruction and compressed fracture at the posterior margin of... |
