摘　　要：目的探讨MRI在脊椎结核诊断及鉴别诊断中的应用价值。方法回顾性分析经手术及组织学证实的79例脊椎结核、肿瘤病例。结果45例脊椎结核MRI表现为椎体骨质破坏、碎裂、间盘受累、椎间隙变窄、椎旁可见软组织肿胀,椎体病变的信号改变,间盘病变及椎旁肿胀的信号均呈长T1、略长T2信号,STIR像为高信号。34例脊柱肿瘤椎间盘均未受累,其中15例转移瘤同时累及椎体及附件,2例累及附件。结论MRI在脊椎结核的诊断及鉴别诊断中具有明显的作用,特别是STIR成像显示更加清晰。Objective To investigate the clinical value of MRI in differential diagnosis of spinal tuberculosis. Method We analyzed retrospectively 45 patients with spinal tuberculosis and 34 patients with spinal tumor whose diagnosis were confirmed by surgical operation and histopathology. Results Of 45 cases of spinal tuberculosis,MRI showed destroyed vertebral body and intervertebral discs, narrow intervertebral spaces and paravertebral soft tissue swelling. The lesions showed low signal intensity in T1W, and a little bitter high signal intensity in T2W, and high signal in short-tau inversion recovery（STIR）. In 34 cases of vertebral tumor, MRI showed that the vertebral spaces were normal,both vertebral bodies and pedicles were involved in 15 cases,only pedicles were involved in 2 cases. Conclusion MRI is a useful tool in differential diagnosis of spinal tuberculosis, especially STIR images are very clear.
