MRI联合PET-CT诊断胶质瘤的价值分析

目的探讨磁共振成像(MRI)联合正电子发射断层扫描-计算机断层扫描(PET-CT)诊断胶质瘤的临床应用价值。方法选择医院2015年7月至2018年7月收治的疑为胶质瘤患者70例,所有患者均进行MRI和PET-CT检查,以病理学结果为"金标准",对比MRI与MRI联合PET-CT诊断的敏感度、特异度、准确性及Kappa值,并采用ROC曲线分析两种检查在评估胶质瘤中的价值。结果 MRI检查胶质瘤的敏感度为90.48%,特异度为71.43%,准确度为88.57%,Kappa值为0.494;MRI联合PET-CT检查胶质瘤的敏感度为98.41%,特异度为85.71%,准确度为97.14%,Kappa值为0.841。MRI联合PET-CT诊断与病理学结果的一致性明显高于MRI(P<0.05)。ROC曲线分析显示,MRI联合PET-CT预测胶质瘤的敏感度高于MRI(P<0.05)。结论 MRI联合PET-CT可提高检测胶质瘤的敏感度、特异度及准确度,具有较高的预测价值。

Value of MRI Combined with PET-CT in the Diagnosis of Glioma

Objective To explore the clinical application value of magnetic resonance imaging(MRI) combined with positron emission tomography-computed tomography(PET-CT) in the diagnosis of glioma.Methods70 cases of patients suspected as glioma admitted to the hospital from July 2015 to July 1818 were selected.All patients were given MRI and PET-CT.The pathological results were used as the gold standard,and the sensitivity,specificity,accuracy and Kappa value of MRI and MRI combined with PET-CT were compared,and ROC curve was used to analyze the value of the two examinations in the evaluation of glioma.Results The sensitivity,specificity,accuracy and Kappa value of MRI for glioma were 90.48%,71.43%,88.57% and 0.494.The sensitivity,specificity,accuracy and Ka ppa value of MRI combined with PET-CT for glioma were 98.41%,85.71%,97.14% and 0.841.The consistency of MRI combined with PET-CT with pathological results was significantly higher than that of MRI(P<0.05).ROC cu rve analysis showed that the sensitivity of MRI combined with PET-CT for predicting glioma was higher than that of MRI(P<0.05).Conclusion MRI combined with PET-CT can improve the sensitivity,specificity and accuracy in the detection of glioma,and it has a high predictive value.
