目的 比较X线、多层CT、MRI对 脊柱结核患者病灶显示及诊断价值。方 法 以我院2013年1月-2015年6月经病理证 实的30例脊柱结核患者为研究对象，对其 影像学资料(X线、多层CT、MRI)进行回顾 性分析，与病理结果比较，观察其影像学 表现的同时比较三者对脊柱结核各征象 阳性检出率。结果 MRI、CT对椎间盘受 累、椎旁脓肿及椎管受累阳性检出率均明 显高于对照组，且MRI检出率明显更高， 差异有统计学意义(P＜0.05)；CT对死骨 形成检出率为96.9%，显著高于X线、MRI 的34.4%、31.3%，差异有统计学意义(P ＜0.001)。结论 X线、多层CT、MRI在脊 柱结核诊断中各有优劣，CT对死骨形成检 出率较高，MRI对椎体破坏、椎旁脓肿、 椎间盘及椎管受累诊断有明显优势。

Objective To compare the value of X-ray, multi-slice CT and MRI imaging in displaying and diagnosis of lesions in patients with spinal tuberculosis. Methods 30 cases of patients with spinal tuberculosis confirmed by pathology during January 2013 to June 2015 were treated as the research objects. Their imaging data (X-ray, multi-slice CT and MRI) were retrospectively analyzed and were compared with the pathological results. While the imaging performances were observed, the positive detection rate of the three in the signs of spinal tuberculosis were compared. Results The positive detection rates of MRI and CT in disc spaces involvements, paraspinal abscesses and spinal canal involvements were significantly higher than those in the control group and the detection rate of MRI was significantly higher. The differences were statistically significant (P<0.05). The detection rate of CT in sequestration was 96.9% which was significantly higher than 34.4% and 31.3% of X-ray and MRI and the differences were statistically significant (P<0.001). Conclusion X-ray, multi-slice CT and MRI in the diagnosis of spinal tuberculosis have their own advantages and disadvantages. CT has a higher detection rate of sequestration while MRI has obvious advantages in the diagnosis of vertebral destruction, paraspinal abscesses and spinal canal involvements.
