Diffusion tensor imaging (DTI) and its higher order variants are powerful tools for elucidating brain tissue microstructure, but their processing schemes demand high SNR. The benefits of high field MRI (7 T) can be harnessed to amplify DTI processing or resolution, with the right strategy. Two single-shot sequences, echo-planar (EPI) and turbo spin echo (TSE) are often used for diffusion, but their migration to 7 T is ongoing and nontrivial. We present a validation study successfully achieving high quality DTI brain data from both sequences at both 3 T and 7 T through a combination of parallel imaging and post-processing.
