Researchers have developed a new framework for systematically analyzing the effectiveness of Transformer and Recurrent Neural Network (RNN) models in diffusion MRI (dMRI) tractography. The study introduces a generation-validation phase that allows for streamline-level supervision during training, addressing the challenge of aligning local loss functions with global streamline quality. Utilizing the ISMRM2015 tractography challenge dataset, the proposed models achieved state-of-the-art performance and demonstrated applicability to in vivo data from the TractoInferno database. The findings offer insights into the capabilities and limitations of sequence-based deep learning for tractography, along with recommendations for future research. AI
