Firstly, radiomics features were extracted from CE-T1, T2, and 1-cm-thick tumor-to-brain interface (BTI) images. Then, difference analysis and the least absolute shrinkage and selection operator  were orderly used to select the most representative features. Next, the support vector machine algorithm was conducted to predict the WHO\u00a0grade of meningioma. Furthermore, a nomogram incorporated radiomics features and valuable clinical indicators was constructed by logistic regression. The performance of the nomogram was assessed by calibration and clinical effectiveness, as well as internal validation.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Peritumoral edema volume and gender are independent risk factors for predicting meningioma grade.

Then, a nomogram with a pooled AUC\u2009=\u20090.912 (95% CI, 0.876\u20130.961), combined radiomics score, peritumoral edema volume, and gender improved diagnostic performance compared to radiomics model or clinical model and showed good calibration as the true results.
