脊柱结核CT、MRI诊断优势选择

目的：分析脊柱结核的CT、MRI表现，比较两种技术的诊断优势。方法：对手术病理证实的18例患者脊柱结核的CT、MRI资料进行回顾性分析。结果：CT能较好地显示骨质破坏、骨质增生硬化、死骨及新生骨形成、椎间隙狭窄、椎旁软组织肿胀／肿块和腰大肌脓肿、骨性椎管狭窄及钙化，但不如MRI敏感。而对椎问盘受累及脊椎结核早期变化的评估＇椎旁软组织肿胀／肿块的范围准确评估，MRI占明显优势。结论：cT与MRI结合检查可全面反映脊柱结核的影像学特征，有利于脊柱结核的诊断和鉴别诊断。

Research on advantage chooses of CT and MRI in diagnosing spine tuberculosis

Objective： To analyze manifestation of spine tuberculosis in CT and MRI, compare two kinds of techniques respectively of diagnosis advantage. Methods： Retrospective analysis of 18 cases confirmed by the surgical operation and pathology imaging of CT and MRI Material of spine tuberculosis. Results： The CT can nicely show that the bone destruction, the bone increase osteoslerosis, sequester and new-born formation and narrow of intervertebral disc swelling paraspinal soft tissue and psoas major muscle abscess, spinal canal of bone is narrow,calcification. Although CT can show intervertebral disc involvement and terminal plate of vertebral body destruction in sagittal reconstruction, not equal to MRI sensitive, Evaluating intervertebral disc involvement and area of paraspinal soft tissue swells, changed in early days spine tuberculosis of valuation, MRI had obvious advantage. Conclusion： Combining CT and MRI can reflect the image of spine tuberculosis to learn a characteristic completely and be advantageous to diagnosing and discriminate diagnosis of spinal tuberculosis.
