SPECT/CT与MRI鉴别脊柱结核与脊柱肿瘤的价值观察

Value of SPECT/CT and MRI in Identifying Spinal Tuberculosis and Spinal Tumors

目的探究脊柱结核与脊柱肿瘤采用SPECT/CT与MRI进行鉴别的价值差异。方法回顾分析我院2018年5月至2019年5月期间收治67例脊柱病变患者相关资料,患者均接受SPECT/CT、MRI检查及病理检查。比较SPECT/CT、MRI判断脊柱结核以及肿瘤符合率、诊断脊柱结核情况、脊柱结核与脊柱肿瘤诊断价值。结果以病理结果作为"金标准",SPECT/CT与MRI诊断脊柱结核和肿瘤诊断符合率分别为87.88%、98.48%,差异比较具有统计学意义(P<0.05);SPECT/CT与MRI诊断脊柱结核椎休损伤差异没有统计学意义(P>0.05),SPECT/CT对死骨检出率高于MRI,椎间盘受累以及椎旁脓肿检出率低于MRI,差异有统计学意义(P<0.05);SPECT/CT诊断脊柱结核以及肿瘤灵敏度、特异度、准确度分别为47.62%、95.33%、78.79%,MRI诊断脊柱结核以及肿瘤灵敏度、特异度、准确度分别为85.71%、95.56%、92.42%。结论SPECT/CT与MRI均可用于鉴别脊柱结核和脊柱肿瘤,但MRI诊断价值优于SPECT/CT。

Objective To explore differences in value of sPECT/CT and MRI for identifying spinal tuberculosis and spinal tumors.Methods The relevant data of 67 patients with spinal lesions who were admitted to the hospital from May 2018 to May 2019 were retrospectively analyzed.All underwent sPECT/CT and MRI.After imaging examination,pathological examination was performed.The coincidence rates of sPECT/CT and MRI for determining spinal tuberculosis and tumors,diagnostic value of the two for spinal tuberculosis and spinal tumors were compared.Results Taking pathological results as"golden standard",coincidence rates of sPECT/CT and MRI in diagnosis of spinal tuberculosis and tumor were 87.88%and 98.48%,respectively(P<0.05).There was no significant difference between sPECT/CT and MRI in diagnosis of spinal tuberculosis vertebral injury(P>0.05).The detection rate of dead bones by sPECT/CT was higher than that by MRI,while detection rates of intervertebral disc involvement and paravertebral abscess were lower than those by MRI(P<0.05).The sensitivity,specificity and accuracy of sPECT/CT and MRI for diagnosis of spinal tuberculosis and tumors were(47.62%,95.33%,78.79%)and(85.71%,95.56%,92.42%),respectively.Conclusion Both sPECT/CT and MRI can be applied to identify spinal tuberculosis and spinal tumors.However,diagnostic value of MRI is better than that of sPECT/CT.
