胸椎结核的比较影像学分析

Comparison of thoracic spine tuberculosis Imaging Analysis

目的：探讨胸椎结核的影像学特征。方法：总结胸椎结核的影像学表现，探讨其比较影像学特征。结果：回顾性分析111例胸椎结核的影像学表现均有不同程度的骨质破坏。其中：中心型12例，占10．8％；骨骺型81例，占72．9％。最常见，以椎体及骨骺破坏明显，椎旁均见有不同程度稍低密度软组织肿胀，部分并可见小片状及沙粒状高密度影；骨膜下型15例，占13．5％，常见于胸椎椎体前缘；附件型3例，占0．27％，发生于两侧横突.结论：比较影像学能够较好地显示胸椎结核特征性表现，CT在椎体及附件骨质破坏程度、椎管受累、椎旁软组织范围方面优于常规X线平片检查，且对死骨片、骨质硬化及冷脓肿内钙化显示优于MR1。MR1在椎管受累、椎旁软组织范围方面优于CT及常规X线平片检查，X线在分型及定位方面较准确。

Objective：Of the imaging features of thoracic tuberculosis. Methods： The imaging manifestations of thoracic tuberculosis and explore its comparative imaging features. Results： Retrospective analysis of 111 cases of thoracic imaging manifestations of tuberculosis have different degrees of bone destruction. Of which： central type in 12 cases, 10.8% ; Epiphysis type 81 cases, accounting for 72.9%, the most common Significant damage to vertebrae and epiphyseal, paravertebral slightly different degrees were observed in low--density soft tissue swelling, and can see small pieces and some sand granular high density; Subperiosteal in 15 cases, accounting for 13. 5%, common in front thoracic vertebrae% Annex 3 cases, accounting for 0. 27%, occurred in both sides of transverse process. Conclusion： Better able to compare imaging features of spinal tuberculosis show the performance of CT and accessories in the vertebral bone damage, spinal involvement, the scope of paraspinal soft tissue better than conventional X--ray examination And on the sequestrum films, bone sclerosis and calcification of cold abscess is superior to MRI. MRI in the spinal canal involvement, the scope of paraspinal soft tissue better than CT and conventional X--ray examination, X line in the classification and positioning more accurate.
