Summary of data generation and study design. A The summary of data generation. One-hundred thirteen UIA patients receiving neuro-interventional surgery were included as the derivation cohort, and 40 patients were included as the validation cohort. B Study design. In this study, we firstly established a CNN model to automatically measure the morphological features of UIAs using the U-Net algorithm. Subsequently, a NFM model was established for recommending the diameter of first coils. UIA, intracranial aneurysm; CNN, convolutional neural network; NFM, neural factorization machines
