| 摘 要： | 本文分析了15例脊柱结核的MRI表现及其强化特征。结果显示:T_1及T_2加权像病变椎体有广泛的信号改变,病变椎同盘T_2加权像为高信号,15例均有椎旁软组织肿块和脓肿形成。Gd-DTPA增强检查,见椎体骨内脓肿、脊膜受累、病变沿韧带下扩散及椎旁软组织肿块和脓肿显示良好,增强检查能够提供MRI平扫不能得到的较有特征的表现。

| Abstract: | Magnetic resonance images (MRI) of 15 patients with tuberculosis spondylitis (TS) were analyzed, and the features of contrast enhancement were also e-valuated. The following results were observed:All affected vertebrae showed diffuse abnormal signal intensity. The involved disc increased in signal on T2-weghted images. The paraspinal mass and abscess were seen in all cases where there were destruction of vertebral body and intervertebral disc. Vertebral intraosseous abscesses, meningeal involvement, subligamentous spread, paraspinal abscess and mass formation were identified well on contrast-enhanced studies. Post-Gd-DTPA images showed important features of TS that were unobtainable with T1 and T2-weighted imaging. |
