摘      要：Objective To observe the value of grey-level histogram analysis based on T2WI for differentiating consistency of *** Data of 109 patients with meningioma were retrospectively *** patients were divided into hard group(n=71)and soft group(n=38)according to the consistency of *** ROI was outlined on axial T2WI showing the largest tumor section,gray levels were extracted and histogram analysis was *** value of each histogram parameter were compared between *** receiver operating characteristic curve was drawn,and the area under the curve(AUC)was calculated to evaluate the efficiency for differentiating soft and hard *** P 1,P 10,P 50,P 90,P 99 and the mean grey levels on T2WI in soft group were all higher than those in hard group(all P0.05).The differentiating efficiency of P 1,P 10,P 50,P 90,P 99 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 P0.05).Conclusion Parameters of grey-level histogram analysis such as P 1,P 10,P 50,P 90,P 99 and the mean values based on T2WI were all valuable for differentiating soft and hard meningioma.
