Multi-parametric qualitative and quantitative MRI assessment as predictor of histological grading in previously treated meningiomas

ConclusionOur multi-parametric MRI assessment showed high sensitivity and specificity in predicting histological grading of meningiomas. Such an assessment may be clinically useful in characterizing lesions without histological diagnosis.Key points•When surgery and biopsy are not feasible, parameters obtained from both conventional and diffusion-weighted MRI can predict atypia and anaplasia in meningiomas with high sensitivity and specificity.•Low ADC values and heterogeneous contrast enhancement are the best predictors of higher grade meningioma
