Disclosed, according to one embodiment of the present disclosure, is a medical image-based disease prediction method carried out by a computing device. The method may comprise the steps of: by using a pre-trained first model, generating a feature vector comprising respective brain disease prediction values for two-dimensional medical images included in a three-dimensional medical image; by using a pre-trained second model, and on the basis of the feature vector, estimating respective importances, indicating prediction accuracy, for the two-dimensional medical images; and, on the basis of the importances, selecting, among the two-dimensional medical images, at least one model input image suitable for predicting the brain disease.
