In this study, we applied various ML techniques, including random forest (RF), XGBoost (XGB), support vector machines (SVM), and multi-layer perceptron (MLP), to predict IA rupture status.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st2\">\n<jats:title>Methods: <\/jats:title>\n<jats:p>The dataset consisted of 178 IAs each with 53 clinical and radiographic features for analysis. We removed features with high correlation (&gt;0.8) with respect to the target variable to reduce redundancy. We applied grid search to fine-tune the hyperparameters for each model. Each model was evaluated across five iterations of 5-fold cross-validation. Overall performance metrics (accuracy, precision, recall, and F1-score) were extracted. The Wilcoxon signed-rank test was used to compare the area under the curve (AUC) scores between models.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Results: <\/jats:title>\n<jats:p>The most common locations were internal carotid artery (42), anterior communicating artery (41), middle cerebral artery (32), and posterior communicating artery (25). The AUC for the RF (0.85) and XGB (0.76) models were significantly higher than those for the SVM (0.69) and MLP (0.65) models (<jats:italic>P<\/jats:italic> &lt; 0.05). There was no statistical difference in accuracy between RF and XBG models (<jats:italic>P<\/jats:italic> = 0.144). Fractal dimension ranked as the most important feature for model performance across all models. Three-dimensional (3D) shape features made up 8 of the 15 most important features driving model performance.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st4\">\n<jats:title>Conclusion: <\/jats:title>\n<jats:p>Among the models, RF achieved the highest accuracy (85%) with balanced precision and recall. Across models 3D geometric features drove model performance, highlighting the importance of these features in predicting rupture status.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_498_2025","type":"journal-article","created":{"date-parts":[[2025,7,18]],"date-time":"2025-07-18T08:51:06Z","timestamp":1752828666000},"page":"298","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Using
