A subset of meningiomas may show early progression/recurrence (P/R) after surgery. In clinical practice, one of the main challenges in the treatment of meningiomas is to determine factors that correlate with P/R. This study investigated the role of preoperative MR radiomics and apparent diffusion coefficient (ADC) value for prediction of P/R in meningiomas. The four most significant radiomic features selected by support vector machine (SVM) were used to calculate SVM score for each patient. High SVM score and low ADC value were associated with early P/R and short progression-free survival in meningiomas.
