Flowchart of the study process depicting patient selection and study design. The “Random” model was initialized by using the method described by He et al (26). Performance analysis for assessment of model generalization was evaluated at section level (convolutional neural networks 1 [CNN-1] and 2 [CNN-2]). Patient-level prediction for diagnostic accuracy was performed with training and testing dataset from both scanners. SB = data from both scanners (scanner 1 plus scanner 2); val = validation datasets.
