螺旋CT在胸椎小关节紊乱诊断中的运用

Application of Spiral CT on Diagnosis of Thoracic Vertebra Small Joint Disorder

目的:探讨螺旋CT对胸椎小关节紊乱诊断的优越性。方法:对98例不明原因引起胸背痛的患者分别进行X线平片和CT检查,重点观察胸椎三种小关节间隙改变情况、局部硬化情况和周围软组织变化情况。找出胸背痛的真正原因。同时比较两种检查方法的优势。结果:98例患者有88例因胸椎小关节紊乱引起,CT对小关节间隙改变和局部硬化情况检查率为100%,X线平片因经验和误差造成检查率有所降低,但差异无统计学意义(P>0.05)。CT能检查出周围软组织病变,但X线平片无法完成,差异有统计学意义(P<0.05)。10例胸背痛患者并无胸椎小关节病变,而是由于其他系统疾病诱发。结论:16排CT在胸椎小关节紊乱诊断中具有高检测率,对软组织病变检查优于X线平片。

Objective：To discuss the superiority of spiral CT on the diagnosis of thoracic vertebra small joint. Methods：Used X-ray and CT to exam the 98 patients with chest pain unexplained, focus on the three small joints of thoracic spinal with changes of joint space, part of harden and soft tissue changes. Found out the real reasons of chest pain.and then compared the advantages of the two methods. Results：88 of 98 patients had chest pain caused by thoracic spinal facet disorder, the examination rate of CT for small joints with joint space and local harden was 100%, the rate of X-ray decreased becaused of experience and the error, but the difference was not statistically significant（P〉0.05）.CT can check out the surrouding soft tissue lesions,but X-ray can not complete, the difference was statically significant（P〈0.05）.10 cases of chest pain patients without thoracic spinal facet lesions, due to induce other diseases. Conclusion：16 rows of CT had high detection rate on the diagnosis of thoracic spinal facet disorder, was more superior than X-ray for soft tissue lesions.
