摘　　要：目的:评价X线平片、CT和MRI诊断腰椎结核的效果。方法:回顾性分析40例腰椎结核和52例其它腰椎疾病患者的影像学资料,比较其常用的诊断指标。结果:在诊断腰椎结核的正确率方面,MRI(94.6%)最高,CT(82.6%)次之,X线平片(71.7%)最低,差异均有统计学意义(P<0.05)。在诊断腰椎结核的灵敏度方面,MRI(95.0%)高于X线平片(62.5%)和CT(77.5%),差异均有统计学意义(P<0.05);但X线平片与CT之间的差异无统计学意义(P>0.05)。在诊断腰椎结核的特异度方面,MRI(94.2%)高于X线平片(78.8%),差异有统计学意义(P<0.05);但MRI与CT(86.5%)及CT与X线平片之间的差异无统计学意义(P>0.05)。结论:X线平片、CT和MRI在诊断腰椎结核方面各具优势,实际工作中应充分利用这三种影像学检查方法的优势,以X线平片检查为基础,辅以CT和MRI检查,为更准确地诊断腰椎结核提供影像学依据。Objective： To evaluate the result of X-ray, CT and MRI in the diagnosis of tuberculosis of lumbar spine. Methods： A retrospective analysis of 40 cases of tuberculosis of lumbar spine and 52 cases of other diseases of lumbar spine was conducted, and the common diagnostic indexes were then compared. Results： In the diagnostic accuracyof tuberculosis of lumbar spine, MRI（94.6%） was highest, CT（82.6%） secondary, X-ray（71.7%） lowest, all the differences were significant（P〈0.05）. In the diagnostic sensitivity, MRI（95.0%） is higher than X-ray（62.5%）and CT（77.5%）, the differences were significant（P〈0.05）; But the difference between X-ray and CTwas not significant（P〉0.05）. In the diagnostic specificity, MRI（94.2%） is higher than X-ray（78.8%）, the difference was significant（P〈0.05）; But the differences between MRI and CT（86.5%）, and between X-ray and CT were not significant（P〉0.05）. Conclusions： X-ray, CT and MRI had respective advantage in the diagnosis of tuberculosis of lumbar spine, CTand MRI should beappropriatelyused on thebasisofX-rayin clinicalwork.
