目的探讨X射线、CT及MRI对于术后早期椎间隙感染的诊断价值。方法 7例临床明确诊断的术后早期椎间隙感染患者均行X线、CT及MRI检查。结合临床治疗,定期随访;对所有影像学资料进行总结,比较分析患者症状、体征、白细胞、高敏C反应蛋白以及血沉的变化。结果 7例患者的X射线检查无异常(除去手术去除骨质)、CT可显示椎间盘及周围组织有异常信号,边界模糊;MRI可以清楚地看到在椎间盘、椎体、椎旁软组织信号异常。结论MRI可清晰显示椎间隙感染病变组织,对椎间隙感染早期诊断和鉴别存在重要意义,是目前诊断术后早期椎间隙感染的最佳影像学检查方法。
Objective To investigate the diagnostic value of X-ray, CT and MRI in early postoperative infection of intervertebral space. Methods Seven cases of early postoperative patients with intervertebral infection with definite diagnosis were examined by X-ray, CT and MRI. Combined with clinical treatment, regular follow-up; to summarize all the imaging data, comparative analysis of the patient’s symptoms, signs, white blood cells, high sensitivity C-reactive protein and erythrocyte sedimentation rate changes. Results Seven patients had no X-ray abnormalities (except surgery to remove bone). CT showed abnormal signals of intervertebral disc and surrounding tissues with fuzzy boundaries. MRI showed abnormal signals in the soft tissue of intervertebral disc, vertebral body and vertebra. Conclusion MRI can clearly show the pathological changes of intervertebral space infection. It is of great significance in the early diagnosis and differential diagnosis of intervertebral space infection. It is the best imaging method for the diagnosis of early postoperative intervertebral space infection.
