Establishment of an automatic morphological measurement model. A The flowchart of establishing CNN model to identify and segmentate UIAs. B The manual and model delineation images of representative cases. C The violin plots present the distribution of dice, F2, precision, and recall value within the testing set (n = 40). D The scatter dot plots present the correlation of aneurysm size and height measured by model and doctors. UIA, unruptured intracranial aneurysm; CNN, convolutional neural network
