Slice accelerated (multiband) DTI shows great potential
for reducing scan times of lengthy acquisitions.
Multiband imaging can provide significant time saving in
long scans, such as high angular diffusion resolution
imaging (HARDI) acquisition. DTI-based tractography
seeded in the corpus callosum on the mid-sagittal slice
were performed, showing comparable results for
accelerated HARDI. This study shows that slice
accelerations of 2-3 can be used to reduce the otherwise
long scan time of HARDI to clinically feasible times,
without losing image quality.
