Four patients with spinal epidural sepsis were evaluated with MR imaging. The lesions were best visualized with spin-echo techniques with long repetition (2000 msec) and long echo (80-100 msec) times. Sagittal and axial images were equally important in defining the extent of the lesions. Comparison with available contrast-enhanced CT scans showed that MR was more definitive in the early demonstration of the abscesses. This early recognition influenced the management greatly and improved the clinical outcome significantly. The findings in our four cases support previous reports that MR is superior to other imaging methods for early recognition and anatomic localization of infectious diseases in patients suspected of having either spinal osteomyelitis or spinal epidural sepsis.
对4例脊柱硬膜外脓肿患者进行了磁共振成像（MR）评估。采用长重复时间（2000毫秒）和长回波时间（80 - 100毫秒）的自旋回波技术能最佳显示病变。矢状位和轴位图像对于确定病变范围同样重要。与现有的增强CT扫描结果对比显示，MR在脓肿的早期显示方面更具确定性。这种早期识别对治疗管理有很大影响，并显著改善了临床结局。我们4例患者的研究结果支持了之前的报道，即对于怀疑患有脊柱骨髓炎或脊柱硬膜外脓肿的患者，MR在传染病的早期识别和解剖定位方面优于其他成像方法。
