In this study, we evaluated the potential of diffusion-weighted imaging (DWI) at ultrahigh field strength with regard to the total acquisition time, the spatial and the angular resolution and the coverage using a state of the art 7T MR scanner.
Whole brain DWI with an isotropic resolution of 1.2 mm is feasible without averaging in a total acquisition time acceptable for clinical applications (less than four minutes). The high resolution unveils anatomical details, such as the radial anisotropy of the cortex.
No relevant competing interests disclosed.
