Abstract:
Objective To observe the value of grey-level histogram analysis based on T2WI for differentiating consistency of meningioma.Methods Data of 109 patients with meningioma were retrospectively analyzed.The patients were divided into hard group(n=71)and soft group(n=38)according to the consistency of tumors.Tumor ROI was outlined on axial T2WI showing the largest tumor section,gray levels were extracted and histogram analysis was performed.The value of each histogram parameter were compared between groups.Then receiver operating characteristic curve was drawn,and the area under the curve(AUC)was calculated to evaluate the efficiency for differentiating soft and hard meningioma.Results P1,P10,P50,P90,P99 and the mean grey levels on T2WI in soft group were all higher than those in hard group(all P＜0.05),while the variance,the kurtosis and the skewness were not significantly different between groups(all P＞0.05).The differentiating efficiency of P1,P10,P50,P90,P99 and the mean grey levels on T2WI were all fine,with AUC of 0.774 to 0.833,and no significant difference was found(all P＞0.05).Conclusion Parameters of grey-level histogram analysis such as P1,P10,Ps0,P90,P99 and the mean values based on T2WI were all valuable for differentiating soft and hard meningioma.
