Abstract
Objective:To investigate the value of MR diffusion weighted imaging(DWI) in the differential diagnosis of high and low-grade meningioma.Methods:Thirty-one patients with low-grade meningioma (WHO Ⅰ) and 25 patients with high-grade meningioma(WHO Ⅱ～Ⅲ) were enrolled in this study,the DWI data were retrospectively analyzed.The patients were divided into low-grade group and high-grade group,and ADC values were measured separately.The difference in ADC value was compared between two groups.The ROC curve was drawn,and the cutoff value for the high-grade meningioma detection was determined.Results:The ADC value of high and low-grade meningioma was (0.72+0.10)×10-3mm2/s,(0.93+0.12)×10-3mm2/s respectively,the ADC value of high-grade meningioma was significantly lower than that of low-grade meningioma,the difference was statistically significant (t=7.30,P＜0.01);ROC curve analysis showed that the ADC value for the best critical point of diagnosis for high-grade meningioma was 0.83×10-3mm2/s.The sensitivity was 84％,specificity was 80.6％,accuracy was 82.1％.Conclusion:MR DWI ADC has high value in the differential diagnosis of high and low-grade meningioma,which can provide more information for treatment and prognostic evaluation.关键词
