Fig. 1From: What benefit can be obtained from magnetic resonance imaging diagnosis with artificial intelligence in prostate cancer compared with clinical assessments?Pipeline of the classification process of artificial intelligence. There are three discrete steps in the pipeline: inputting images (i.e., image acquisition and pre-processing), model development, and model performance validation. Generally, there are two main approaches to developing AI models: the hand-crafted radiomics method and the deep learning radiomics method. For the hand-crafted radiomics model, there are four steps: annotation, feature extraction, feature selection and modeling with traditional machine learning methods. For the deep learning radiomics model, the images can be fed into the end-to-end model to output the risk probability of adverse outcomes.
