Machine Learning Prediction of Aneurysm Rupture Risk Based on the Fusion of Hemodynamic and Morphological Features
本研究旨在通过整合动脉瘤患者的血流动力学与形态学特征,构建一个预测动脉瘤破裂风险的机器学习模型。收集了2021年2月至2023年12月期间在牡丹江医学院附属红旗医院神经外科就诊的颅内动脉瘤患者的病例。研究组包括130例动脉瘤破裂患者,对照组包括60例未破裂的动脉瘤患者。所有患者均提供了DICOM格式的CT(Computed Tomography)图像,并在获得医院伦理委员会的批准和患者家属签署知情同意书后,使用MIMICS软件对动脉瘤的DICOM格式CT影像进行了三维重建。通过形态学测量,我们获得了形态学参数指标,并通过计算流体力学仿真计算得到了血流动力学参数。将形态学参数与血流动力学参数相结合,构建了一个用于机器学习临床预测模型的数据集。研究采用了10种机器学习算法构建预测模型,并使用准确率、AUC(Area Under Curve)、召回率和
The aim of this study is to construct a machine learning model for predicting the risk of aneurysm rupture by integrating hemodynamic and morphological features of patients with intracranial aneurysms. Cases of patients with intracranial aneurysms who sought treatment at the Department of Neurosurgery
Affiliated Hongqi Hospital of Mudanjiang Medical University from February 2021 to December 2023 we
re collected. The study group comprised 130 patients with ruptured aneurysms
while the control group included 60 patients with unruptured aneurysms. All patients provided CT (Computed Tomography) images in DICOM format
and after obtaining approval from the hospital’s ethics committee and signed informed consent from the patients’ families
three-dimensional reconstruction of the aneurysm DICOM format CT images was performed using MIMICS software. Morphological parameters were obtained through morphological measurements
and hemodynamic parameters were calculated through computational fluid dynamics simulations. The dataset for constructing the machine learning clinical prediction model was built by combining morphological and hemodynamic parameters. Ten machine learning algorithms were employed to construct the prediction models
and their performance was evaluated using metrics such as accuracy
AUC (Area Under the Curve)
recall rate
and
F
1
score. Additionally
model interpretability was analyzed using the SHAP method. Among all the models tested
the random forest model demonstrated the best performance with an accuracy of 0.78
an AUC value of 0.81
and a high recall rate of 0.72. The machine learning model constructed by integrating the morphological and hemodynamic features of aneurysms can provide a powerful tool for clinical decision-making and shows promising potential for clinical application.
