Illustration of the study workflow. Clinical and imaging data of the potential candidates were collected and assessed for enrollment eligibility. The aneurysms were segmented by two radiologists using 3D slicer software. Seven groups of radiomics features were extracted using Artificial Intelligence Kit (AK). The feature number was reduced using a step-wise process. The selected radiomics features were used to build the radiomics model. The model was evaluated using the area under receiver operating characteristic curve on training and test cohorts.
