摘　　要：目的探讨磁共振成像(MRI)平扫联合增强扫描对脑膜瘤的临床诊断价值。方法回顾性分析2021年1月至2023年8月本院收治的90例脑膜瘤患者,均接受T1WI、T2WI序列平扫和T1WI增强扫描。分析90例脑膜瘤患者手术病理情况;比较不同病理亚型脑膜瘤患者的MRI平扫和增强扫描的T1WI、T2WI信号及强化特征;比较MRI平扫联合增强扫描对脑膜瘤病灶的检出率与手术病理结果;分析脑膜瘤患者典型病例的MRI平扫和增强扫描典型病例影像学特征。结果90例脑膜瘤患者经手术病理确诊WHO I级81例,其中纤维型14例、上皮细胞型39例、血管瘤型7例、过渡型21例,脑膜瘤WHOⅡ级9例,均为非典型脑膜瘤;各病理亚型脑膜瘤患者的T1WI信号强度比较,差异无统计学意义(P>0.05);各病理亚型脑膜瘤患者的T2WI信号强度和增强扫描强化程度比较,差异有统计学意义(P<0.05);MRI平扫联合增强扫描对脑膜瘤病灶检出率为94.44%,与手术病理诊断结果比较,差异无统计学差异(P>0.05)。结论MRI平扫联合增强扫描在脑膜瘤的定性及定位诊断中具有较好的应用价值,值得临床推广。Objective To explore the clinical diagnostic value of magnetic resonance imaging(MRI)plain scan combined with enhanced scan in meningioma.Methods A total of 90 patients with meningioma admitted to the hospital were retrospectively analyzed between January 2021 and August 2023,and all underwent T1WI,T2WI plain scans and T1WI enhanced scan.The surgical pathology in the 90 patients with meningioma was analyzed.T1WI and T2WI signals,and enhancement characteristics of MRI plain scan and enhanced scan in patients with different pathological classifications of meningioma were compared.The detection results of meningioma lesions by MRI plain scan combined with enhanced scan and pathological examination was compared.The imaging classifications of MRI plain scan and enhanced scan in typical cases of meningioma patients were analyzed.Results In the 90 patients with meningioma,surgical pathology showed that there were 81 cases with WHO grading at grade I(including 14 cases with fibrous type,39 cases with epithelial cell type,7 cases with hemangioma type and 21 cases with transitional type)and 9 cases at grade II(atypical meningioma).There was no significant difference in signals intensity on T1WI among patients with different pathological classifications of meningioma(P>0.05),but there were significant differences in signals intensity on T2WI and enhancement degree of enhanced scan(P<0.05).The detection rate of meningioma lesions by MRI plain scan combined with enhanced scan was 94.44%,and the difference was not statistically significant compared with that by surgical pathology(P>0.05).Conclusion MRI plain scan combined with enhanced scan has good application value in the qualitative and localization diagnosis of meningioma,which is worthy of clinical promotion.
