摘要
目的 探讨MRI、CT、X线三种影像学检查方法对脊柱结核病变的诊断价值.方法 回顾性分析2013年2月至2015年6月有完整影像学资料的50例脊柱结核患者,观察患者X线、CT、MRI的影像学表现,比较三种检查方法的诊断价值.结果 CT对脊柱结核诊断的准确率、灵敏度及特异度分别为72.65%、68.88%、72.33%,MRI对脊柱结核检诊断的准确率、灵敏度及特异度分别为86.39%、79.69%、90.25%,均显著高于X线,且MRI的准确率、灵敏度及特异度均显著高于CT,三组间比较差异有统计学意义（P〈0.05）;MRI对患者骨质破坏、椎间隙狭窄、脓肿及椎管受累的检出率分别为98.00%、100.00%、94.00%、88.00%,显著高于X线及CT检查,三组间比较差异有统计学意义（P〈0.05）,CT对钙化的检出率为60.00%,显著高于X线和MRI检查（P〈0.05）.结论 X线平片检查以骨质破坏和椎间隙狭窄为主要表现,是诊断脊柱结核的基础方法,CT可显示病灶部位,对钙化空洞和死骨形成具有较高的诊断价值,MRI可清晰显示病变侵犯的软组织部位,并可提高脊柱结核的诊断准确性,是早期诊断及鉴别的一种可靠的检查方法.
Objective To investigate the diagnostic value of three imaging examination methods （MRI, CT and X-ray） in the diagnosis of spinal tuberculosis lesion.Methods A retrospective analysis of clinical data was carried out in 50 patients with spinal tuberculosis with complete imaging data from February 2013 to June 2015.The imaging performance of X-ray, CT and MRI of patients were observed, and the diagnostic value of three examination methods were compared.Results The accuracy rate, sensitivity, specificity of CT in the diagnosis of spinal tuberculosis was 72.65%, 68.88%, 72.33%, and the accuracy rate, sensitivity, specificity of MRI in the diagnosis of spinal tuberculosis was 86.39%, 79.69%, 90.25%, which were significantly higher than those of X-ray, and the accuracy rate, sensitivity, specificity of MRI was significantly higher than those of CT, there were significant differences among the three groups （P〈0.05）;the detection rate of MRI to destruction of bone, narrowing of intervertebral space, abscessus and spinal canal involvement was 98.00%, 100.00%, 94.00%, 88.00%, which was significantly higher than those of X-ray and CT, there were significant differences among the three groups （P〈0.05）, the detection rate of CT to calcification （60.00%） was significantly higher than that of X-ray and MRI examination （P〈0.05）.Conclusions The main performances of X-ray films are destruction of bone and narrowing of intervertebral space, and X-ray is the basic method for the diagnosis of spinal tuberculosis.CT can display the location of lesions, has a high value in the diagnosis of calcification, cavity and sequestration.MRI can clearly display soft tissue site invaded by lesions, and it can increase the diagnostic accuracy of spinal tuberculosis, is a reliable examination method in the early diagnosis and identification.
