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.
