A total 1,130 features were extracted from T2 fluid-attenuated inversion recovery images, including first-order statistics, 3D shape, texture, and wavelet features. Regions of interest, including the entire tumor and peritumoral edema, were drawn manually. Pearson correlation coefficient, 10-fold cross-validation, area under curve (AUC) analysis, and support vector machine were adopted to select the most relevant features to build a clinical model, a radiomics model, and a clinical\u2013radiomics model for GAE. The receiver operating characteristic curve (ROC) and AUC were used to evaluate the classification performance of the models in each cohort, and DeLong\u2019s test was used to compare the performance of the models. A two-sided <jats:italic>t<\/jats:italic>-test and Fisher\u2019s exact test were used to compare the clinical variables. Statistical analysis was performed using SPSS software (version 22.0; IBM, Armonk, New York), and <jats:italic>p &amp;lt;<\/jats:italic>0.05 was set as the threshold for significance.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The classification accuracy of seven scout models, except the wavelet first-order model (0.793) and the wavelet texture model (0.784), was &amp;lt;0.75 in cross-validation. The clinical\u2013radiomics model, including 17 magnetic resonance imaging-based features selected among the 1,130 radiomics features and two clinical features (patient age and tumor grade), achieved better discriminative performance for GAE prediction in both the training [AUC = 0.886, 95% confidence interval (CI) = 0.819\u20130.940] and testing cohorts (AUC = 0.836, 95% CI = 0.707\u20130.937) than the radiomics model (<jats:italic>p<\/jats:italic> = 0.008) with 82.0% and 78.2% accuracy, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Radiomics analysis can non-invasively predict GAE, thus allowing adequate treatment of frontal glioma. The clinical\u2013radiomics model may enable a more precise prediction of frontal GAE.

GAE.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fonc.2021.725926","type":"journal-article","created":{"date-parts":[[2021,11,22]],"date-time":"2021-11-22T05:19:00Z","timestamp":1637558340000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":25,"title":["Radiomics
