MRI differential diagnosis value of intracranial solitary fibroma/hemangiopericytoma and hemangioma meningioma

Objective To explore the differential diagnosis value of MRI signs for intracranial solitary fibroma/hemangiopericytoma and hemangioma meningioma.Methods The clinical features and MRI signs of SFT/HPC and AM patients confirmed by surgery and pathology were retrospectively analyzed.ROC curve and multivariate Logistic regression model were used to analyze the independent predictors and differential diagnosis efficacy of SFT/HPC and AM.Results T-test of measurement data showed that there were statistically significant differences in age,size,NT1WI,NT2WI,and NDWI between the AM group and the SFT/HPC group(P<0.05).The peritumoral edema was not statistically significant(P>0.05).The chi-square test of the enumeration data showed that the differences in vascular emptying and bone destruction between AM and SFT/HPC were statistically significant(P<0.05),and the meningeal tail sign was not statistically significant(P>0.05).Multivariate logistic regression analysis showed that age,NT1WI,NT2WI and vascular flow were independent predictors of SFT/HPC.The ROC curve analysis of showed that NT1WI and NT2WI can be used to distinguish SFT/HPC and AM,and the discrimination thresholds are 0.7513 and 1.7425,respectively.Conclusion The MRI signs of SFT/HPC and AM are of great value.Age,NT1WI value,NT2WI value,and vascular flow are independent predictors of SPF/HPC.The higher the NT1WI value,the lower the age and the lower the NT2WI value,the diagnosis of SPF/HPC the higher the risk.
