MRI与CT诊断及鉴别脊柱结核与脊柱肿瘤的价值观察

Value of MRI and CT in Diagnosis and Identification of Spinal Tuberculosis and Spinal Tumors

目的比较观察磁共振成像(MRI)、计算机X线断层扫描(CT)对脊柱结核与脊柱肿瘤的诊断及鉴别价值。方法选取本院60例脊柱结核与脊柱肿瘤患者(经病理检查确诊),均接受MRI、CT检查,比较MRI、CT及两者联合对脊柱结核与脊柱肿瘤的诊断灵敏度、特异度、准确性。结果CT鉴别脊柱结核与脊柱肿瘤灵敏度72.22%,特异度87.50%,准确性78.33%,Kappa值0.570;MRI诊断灵敏度77.78%,特异度83.33%,准确性80.00%,Kappa值0.595;两者联合诊断灵敏度97.22%,特异度91.67%,准确性95.00%,Kappa值0.895;CT与MRI联合诊断灵敏度与准确性显著高于CT、MRI诊断(P<0.05)。结论MRI与CT在脊柱结核、脊柱肿瘤诊断中均有较高应用价值,两者联合能够有效提高鉴别准确性。

Objective To compare the value of magnetic resonance imaging(MRI)and computed tomography(CT)in diagnosis and identification of spinal tuberculosis and spinal tumors.Methods 60 patients with spinal tuberculosis and spinal tumors(diagnosed by pathological examination)in the hospital were selected as the subjects.All of them completed MRI and CT examinations.The diagnostic sensitivities,specificities and accuracy rates of MRI,CT,and the combination of the two for spinal tuberculosis and spinal tumors were compared.Results The sensitivity,specificity,accuracy,and Kappa value of CT for identifying spinal tuberculosis and spinal tumors were 72.22%,87.50%,78.33%,and 0.570,respectively.The diagnostic sensitivity,specificity,accuracy,and Kappa value of MRI were 77.78%,83.33%,80.00%,and 0.595,respectively.The sensitivity,specificity,accuracy,and Kappa value of combined diagnosis were 97.22%,91.67%,95.00%,and 0.895.The sensitivity and accuracy of the combined diagnosis of CT and MRI were significantly higher than those of CT or MRI(P<0.05).Conclusion Both MRI and CT have high application value in diagnosising spinal tuberculosis and spinal tumors.The combination of the MRI and CT can effectively improve the diagnostic accuracy.
