脊柱结核的MRI评价

Spinal Tuberculosis: Evaluation with MRI

目的：分析脊柱结核的ＭＲＩ特征。材料和方法：总共１８例证实为脊柱结核的患者行ＭＲＩ检查（男１２例，女６例，年龄１９－７６岁）。结果：ＭＲＩ所见：（１）相邻椎体受累１６例（８８．９％）。（２）韧带下及椎旁脓肿１２例（６６．７％）。（３）椎管内侵犯５例（２７．８％）。（４）１８例共４４个椎体受累，在Ｔ１加权上呈低信号（３４／４４），Ｔ２加权上呈高信号（３２／４４）。（５）１８例中有１６例见椎间盘异常（形态或信号），受累椎间盘在Ｔ２加权上信号多变。结论：脊柱结核的ＭＲＩ征象对诊断极有帮助并能为外科手术提供详细的解剖资料。

Purpose: To analyze MRI features of spinal tuberculosis. Materials and Methods: A total of 18 proven tuberculous spondylitis patients underwent MRI studies (twelve men and six women, aged 19-76 years). Results: MRI findings were: (1) Contiguous vertebrae involvement in 16 cases(88.9%). (2) Subligamental spread and paraspinal abscesses in 12 cases(66.7%);(3) Intraspinal involvement in 5 cases(27.8%);(4) A total of 44 vertebrae were involved,low T1w signal intensity in 34 vertebrae(77.3%)and high T2w signal intensity in 32vertebrae(72.7%);(5) The abnormal of intervertebral disks(shape or signal)were observed in 16 cases and their signal were variable on T2 weighted images. Conclusion: The MRI features of spinal tuherculous are useful for diagnosis and also can offer detailed anatomical inforination for the surgecy.
