Researchers have explored the use of large-scale pretraining to enhance deep learning models for correcting geometric distortions in diffusion-weighted imaging (DWI). The study compared a non-pretrained baseline with self-supervised and generative pretrained models, finding that pretrained models generally outperformed the baseline. However, challenges in transferability were observed when applying the models to data from low- and middle-income countries (LMICs), indicating potential issues with contrast alteration and reliance on anatomical structures. Harmonizing preprocessing steps, such as registering images to a common standard space, showed promise for improving cross-domain deployment. AI
