MSCT联合MRI检查在颅底沟通性脑膜瘤临床诊治中的应用价值分析

Application Value of MSCT Combined with MRI in the Diagnosis and Treatment of Communicating Meningioma of Skull Base

目的分析MSCT联合MRI检查在颅底沟通性脑膜瘤临床诊治中的应用价值。方法回顾分析本院2017年1月至2019年5月收治的39例颅底沟通性脑膜瘤患者的临床资料,所有患者均进行MSCT、MRI检查。对患者所得图像进行分析,以手术后病理结果为基准,比较MSCT、MRI单独检查和联合检查对颅底沟通性脑膜瘤的灵敏度、特异度、准确度以及肿瘤对周围受侵部位(骨质、软组织)诊断符合率。结果在MSCT、MRI单独检查中,比较差异无统计学意义(P>0.05),MSCT+MRI检查敏感性、特异性、准确性明显高于单一检查(P<0.05);MSCT侵犯周围骨质检查准确率(79.48%)优于M RI(56.41%),M RI周围软组织检查准确率(84.61%)优于MSCT(51.28%);而MSCT+MRI在周围骨质、软组织检出准确率分别为94.87%、97.43%,均优于单独检查(P<0.05);在MSCT检查时,肿瘤一般为高密度或等高密度,64.10%(25/39)患者肿瘤周围可见水肿;增强扫描为均匀强化。MRI检查中反馈为稍高长信号或等信号,增强扫描为明显均匀强化。结论MSCT、MRI检查在颅底沟通性脑膜瘤临床诊治中均有一定的应用价值,两者联合诊断可减少误诊和漏诊的情况,可为临床提供更全面的信息。

Objective To analyze the application value of MsCT combined with MRI in the diagnosis and treatment of communicating meningioma of skull base.Methods The clinical data of 39 patients with communicating meningioma of skull base treated in our hospital from January 2017 to May 2019 were retrospectively analyzed.All patients were examined by MsCT and MRI.The images of patients were analyzed.The postoperative pathological results were used as the benchmark.The sensitivity,specificity,and accuracy of the MsCT and MRI alone and combined examinations of them in the diagnosis of communicating meningioma of skull base were compared,and the accuracy in the diagnosis of surrounding invaded sites(sclerotin,soft tissue)invaded by tumor was compared.Results There was no significant difference between the MsCT and MRI(P>0.05).The sensitivity,specificity,and accuracy of MsCT+MRI were significantly higher than those of MsCT and MRI alone(P<0.05).The accuracy of MsCT(79.48%)was better than that of MRI(56.41%)in the diagnosis of invasion of surrounding sclerotin,and the accuracy of MRI(84.61%)in the diagnosis of invasion of surrounding soft tissue was better than that of MsCT(51.28%).The accuracy of MsCT+MRI in detection the surrounding sclerotin and soft tissues was 94.87%and 97.43%,respectively,which were better than the single examinations(P<0.05).In the MsCT examination,tumors were generally high-density or equal height-density,and edema can be seen around the tumor in 64.10%(25/39)patients.The enhanced scan showed uniform enhancement.MRI examination shows slightly higher,longer or equal signals,and enhanced scans showed significant and uniform enhancement.Conclusion MsCT and MRI examinations have some application value in the clinical diagnosis and treatment of communicating meningioma of skull base.The combined diagnosis of them can reduce the misdiagnosis and missed diagnosis and provide more comprehensive information in the clinic.
