For
isotropic high resolution DTI at ultra-high field strength, susceptibility
effects and T2* decay must be properly addressed. A combination of reduced
FOV imaging (zoomed imaging) and parallel imaging is optimized here,
achieving high acceleration factors. This approach enables DWI acquisitions
with 1 mm isotropic resolution at 7T. The high quality of the DTI data
provides a high level of anatomical details.
